Coding gain in wireless communication
WebIntroduction. Ana I Pérez-Neira, Marc Realp Campalans, in Cross-Layer Resource Allocation in Wireless Communications, 2009. 1.3 Considering multiple antennas. In multi-user systems, besides the MUD gain, when terminals are provided with multiple antennas, the spatial diversity (SD) gain and the multiplexing (MUX) gain also play an important role. Webcodes decrease SNR by introducing the coding gain for the communication link. The coding gain measures the amount of additional SNR required to provide the same BER performance for an uncoded message signal (Qian, 1999). xviii In 1948, Shannon proved that for a band limited Additive White Gaussian Noise (AWGN) channel, with

WebPrecoding is a generalization of beamforming to support multi-stream (or multi-layer) transmission in multi-antenna wireless communications. In conventional single-stream beamforming, the same signal is emitted from each of the transmit antennas with appropriate weighting (phase and gain) such that the signal power is maximized at the …
