摘要： An interference cancellation method performed by a receiver includes: determining a strong interference code channel among all code channels that carry a received signal, and determining a signal that corresponds to the strong interference code channel to be a strong interference signal, wherein the received signal has been matched filtered. The method further includes obtaining a reconstructed strong interference signal based on the determined strong interference signal and using a system matrix, performing the interference cancellation for the received signal using the reconstructed strong interference signal, to obtain the signal without interference. The strong interference signal can be reconstructed using the system matrix, and the interference cancellation can be performed for the received signal using the reconstructed strong interference signal. The complexity of inverting the matrix is reduced and the performance is enhanced by reducing the order of the matrix, and thus increasing the efficiency of cancelling the interference.

摘要： According to an embodiment of the invention, a DS-CDMA receiver receives an input signal which comprises a plurality of received signals that are received over a corresponding plurality of antennae. These signals are demodulated and sampled to create digital signals. The digital signals are decorrelated and each of the decorrelated signals are multiplied by a weight to derive weighted estimates. The weighted estimates are summed to generate an estimate of an information symbol. The weights are based upon a cross correlation between the decorrelated signals and a desired signal. According to the invention, this cross correlation may be derived by filtering a pilot signal.

摘要： A method, apparatus, and radio receiver system for canceling multi-user interference in a single-carrier radio communication system. A front-end receiver such as a RAKE receiver receives a radio signal formatted in a sequence of frames, and outputs a plurality of user signals. A processing selector selects on a frame-by-frame basis, either a first signal processing chain that serially decodes and removes the interference contributions of the user signals, or a second signal processing chain that simultaneously decodes and removes the interference contributions of the user signals in parallel. The processing selector may select the first signal processing chain when the number of user signals is greater than or equal to a threshold value, and may select the second signal processing chain when the number of user signals is less than the threshold value.
