摘要： Methods and systems for processing signals in a receiver are disclosed herein and may comprise receiving spatially multiplexed signals via M receive antennas. A plurality of multiple data streams may be separated in the received spatially multiplexed signals to detect MIMO data streams. Each of the MIMO data streams may correspond to a spatially multiplexed input signal.

Complex waveforms, comprising in-phase (I) and quadrature (Q) components for the MIMO data streams within the received spatially multiplexed signals may be processed and the processed complex waveforms may be filtered to generate baseband bandwidth limited signals. Phase and/or amplitude for one or more received spatially multiplexed signals may be adjusted utilizing the estimated complex phase and amplitude. Phase and/or amplitude may be adjusted continuously and/or at discrete intervals.

摘要： Aspects of a method and system for dynamic adaptation and communicating differences in frequency-time dependent systems may include generating a time difference weighting factor and a frequency difference weighting factor, based on at least channel estimates. A time-frequency difference may be computed by forming a weighted sum comprising a time difference and a frequency difference, where forming the weighted sum uses at least the time difference weighting factor and the frequency weighting factor. A channel quality indicator (CQI) feedback message may be generated, comprising the time-frequency difference. The time difference weighting factor and/or the frequency difference weighting factor may be generated adaptively at a base station or a mobile terminal. The time difference and/or the frequency difference may be generated from estimated Signal-to-Noise-Ratios (SNRs) associated with the channel estimates. The SNRs may be based on at least the output of an MMSE receiver.
