摘要： Soft combining in a CoMP or Soft Handover receiver. Usually soft combining implies Maximum Ratio Combining of the per cell equalizer outputs (the demodulated complex symbols). The resulting soft combined complex symbol is then demapped to a produce soft bits, ie Log Likelihood Ratio LLR for each bit. This however is not optimal (noise between cells is correlated) and implies the same equalizer structure per cell as well as a lengthy buffer to align the cells' symbols. It is therefore proposed there to have soft bit combining, ie the LLR of each cell's bits are added together (real values). Per cell synchronization is done as part of the soft bit combining, reducing the buffer length. Each cell path can thereby have its own different equalizer algorithm. A further embodiment further postpone the soft combining at the channel decoder level by replacing the addition of soft bits by non-linear algorithms.
