Limited buffer rate matching
Nettet5G New Radio (NR) is primarily characterized by multi-Gbps throughput and up to 10X lower latency than LTE. 5G adopts Low-Density Parity Check (LDPC) code as the channel coding candidate for data channels. Rate-Matching and Bit-Interleaving functions are performed after LDPC encoding in the transmit signal chain. The purpose of Rate …

In principle, only bits the device can buffer are kept in the circular buffer, that is, the size of the circular buffer is determined based on the receiver’s soft buffering capability. Figure 9.6.
NettetLimited buffer size used for rate matching, specified as a positive integer. The default value corresponds to 384×66, which is the maximum coded length of a code block. The … NettetDescription. out = lteRateMatchTurbo (in,outlen,rv) performs rate matching of input data in to create the output vector out with length outlen. The function performs subblock interleaving, bit collection and bit selection, and pruning defined for turbo encoded data. For more information, see Section 5.1.4.1 of [1].
Nettetout = nrRateMatchLDPC(in,outlen,rv,mod,nLayers) returns the rate-matched output of length outlen for input data matrix in.The input rv is the redundancy version, mod is the modulation type, and nLayers is the number of transmission layers.
