An elaborate coordination among multiple cells called coordinated multipoint (CoMP) transmission/reception is adopted by LTE-A to improve coverage and cell-edge throughput. This paper derives various joint precoding techniques among coordinated cell sites to address the serious co-channel interference (CCI) for downlink CoMP broadband transmission. They include joint time-division multiple access (J-TDMA), joint zero-forcing (J-ZF), joint minimum mean square error (J-MMSE), and joint null-space… CONTINUE READING
