A Code Division Multiple Access (CDMA) downlink receiver based on Adaptive Overlap-Cut (AOC) Method Frequency Domain Equalization (FDE) and non-linear feedback Parallel Interference Cancellation (PIC) is proposed. Firstly, the analysis for the generation and the distribution of the inherent error of Overlap-Cut (OC) Method FDE carries out the improved version of it called AOC Method FDE. Secondly,...
We revisit CDMA downlink receivers (RX) based on linear minimum mean-square error (LMMSE) chip-equalizer front-end followed by a Walsh code correlator for single-input-single (multi)- output (SISO or SIMO) channels with the purpose of highlighting the non-trivial question of bias in the output of the equalizer. In a linear time-invariant channel, this bias is constant at chip-equalizer output, but...
