1. What is BCJR (Bahl, Cocke, Jelinek, and Raviv algorithm)?

The BCJR algorithm is an algorithm. It is characterized by convolutional codes. This algorithm is critical to modern iteratively-decoded error-correcting codes incorporating codes and low-density parity-check codes. The BCJR algorithm is ideal as in it’s anything that increases the a posteriori probability of each bit and the Viterbi algorithm is optimal. In the presence of additive white Gaussian noise, the BCJR algorithm for decoding the output of a multiple-access channel is known as the noisy three-user binary adder channel.

1. What is BCMP (Baskett, Chandy, Muntz, demonstrate, and Palacios)?

BCMP network is a class of queueing networks. The theorem is a significant extension to a Jackson network permitting arbitrary user routing and service time distributions, subject to particular service disciplines.

1. What is  BCP (Best Current Practice)?

A Best Current Practice (BCP) is used for the execution in engineering and data technology. It is more adaptable than a standard since techniques and devices are consistently evolving. The Internet Engineering Task Force distributes Best Current Practice documents in a numbered record series. The Internet standards measure itself is characterized in a progression of BCPs, as is the structure of the IETF, Internet Engineering Steering Group, Internet Architecture Board, and other groups involved in that process.

1. What is BCR (Blocked Call Ratio)?

Block Call Rate is an indicator that is utilized to gauge the percentage of calls blocked because of congestion in the service provider’s network as a ratio of the total number of call endeavors made to access and set up an audio call.

1. What is BCSM (Basic Call State Model)?

A major idea for Intelligent Network control is the basic call state model (BCSM). The call goes through a number of pre-defined phases, at the point when a call is processed by an exchange. The BCSM is a high-level finite state machine description of the Call Control Function (CCF) exercises needed to set up and keep up with communication paths for clients who have Intelligent Network services.

1. What is BCU (Body Central Unit)?

BCU has a significant role in that it is hard-wired into the main networks. Although the Body Central Unit has numerous advantages, simple failures could trigger major problems.  The BCU has to cooperate with several other control units and in this manner needs to adapt loads of signals and messages.

1. What is BD (Billing domain)?

The billing Domain is the segment of the operator network. Billing Domain is situated outside the telecommunication network, which gets and measures CDR files from the core network charging capacities. It incorporates capacities that can provide billing mediation and billing.

1. What is BD (block diagonalization)?

The block diagonalization (BD) is a linear precoding strategy. This block diagonalization is for multi-user multi-input multi-output (MIMO) broadcast channels, which is able to remove the multi-user interference (MUI), but it is not computationally productive. Block diagonalization (BD) based precoding schemes are well-known linear transmit systems.

1. What is BDS (BeiDou Navigation Satellite System?

BeiDou Navigation Satellite System is the Chinese satellite navigation framework. The BDS gives all-time, all-climate, and high-accuracy positioning, navigation, and timing services to worldwide clients. China began to explore a path to develop a navigation satellite system reasonable for its public conditions. It gradually formed a three-step development system. That is; the development of BDS-1 was completed to offer services to China, by 2000; the development of BDS-2 was completed to offer services to the Asia-Pacific region, by 2012; the development of BDS-3 will be completed to offer services worldwide in 2020.

1. What is BE (Bandwidth Efficiency)?

Bandwidth efficiency alludes to the data rate that can be sent over a given bandwidth in a particular communication framework. Spectral efficiency in wireless communications speeds is influenced by the number of clients getting the network simultaneously. The information transfer rate depends on the transmission device’s bandwidth and the transfer signal or the signal-to-noise power ratio. It boosts spectral efficiency and channel capacity when the signal-to-noise ratio is improved. More data must be transmitted over the accessible spectrum to utilize it efficiently.

1. What is BEM (Basis expansion model)?

The utilization of the basis expansion model for channel assessment is proposed for orthogonal frequency division multiple access (OFDMA) system uplinks. The Basis Expansion Model (BEM) is used in a high-speed railway communication scenario for a fast time-varying channel. The channel impulse response is modeled as the sum of basis functions multiplied by various coefficients. Simulation results show that a Generalized Complex-Exponential BEM outperforms a Complex-Exponential. And BEM (CE-BEM) and a polynomial BEM in terms of Mean Squared Error (MSE). The MSE of the CEBEM diminishes as the number of basis functions increases.

1. What is BEM (Block Edge Mask)?

A block-edge mask allowed power levels over the block of the spectrum of interest and its adjoining blocks. A block edge mask is a transmitter spectrum mask. It is applied at the edge of an adjoining authorized block of spectrum and is intended to provide adequate security from interference to any anticipated receiving framework in an adjacent frequency block.

1. What is BER (bit error rate)?

The bit error rate is the number of bit errors per unit time. The bit error ratio is the ratio of the number of bit errors by the total number of sent bits during a time interval. Bit error ratio is expressed as a percentage. Bit Error Rate is utilized as a significant parameter in defining the performance of information channels. When communicating information from one point to another, the key parameter is how many errors will appear in the information that appears at the remote end.
