BER Performance of Multilevel Linear Block Codes with Error Correction on RICIAN Fading Channel

摘要

Linear block codes (LBCs) generally provide good error detection and correction capability, but only transmit one data symbol per time slot. Using higher order modulations incurs high decoding complexity and lengthy code searches. Multi -layer schemes using multiple LBCs over sub -groups of antennas provide higher throughp ut, but require as many receive as transmit antennas and have reduced diversity gains. Here, development of multilevel LBCs that can provide the high throughput of multi -layered schemes while realizing larger diversity gains. Any number of receive antennas can be used. An example is shown that achieves 4 bits/sec/Hz using 16 -QAM and 2 transmit antennas
