    摘要: A method (200) of bias cancellation for a radio channel sequence includes: receiving (201) a radio signal, the radio signal comprising a radio channel sequence coded by a first signature, the first signature belonging to a set of orthogonal signatures; decoding (202) the radio channel sequence based on the first signature to generate a decoded radio channel sequence; decoding (203) the radio channel sequence based on a second signature, wherein the second signature is orthogonal to the signatures of the set of orthogonal signatures, to generate a bias of the radio channel sequence; and canceling (204) the bias of the radio channel sequence from the decoded radio channel sequence.

    摘要: A communication device is provided that includes a receiver configured to receive a radio frequency signal. The communication device further includes a processor configured to determine a shift frequency based on a component radio frequency signal. The processor is configured to determine a second signal based on the radio frequency signal. The component radio frequency signal is dependent from the radio frequency signal and associated with a frequency related to the radio frequency signal represented in the frequency domain. The second signal is determined from shifting frequencies related to the radio frequency signal represented in the frequency domain by the shift frequency.

    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.
