Abstract
Co-channel interference with a desired signal in a receiver arrangement of a TDMA cellular radio communications system having two antennas and receivers for providing two received signals is reduced. Two sampled signals are derived from each of the two received signals by sampling the respective received signal at twice the symbol rate of the system and separating alternate samples at twice the symbol rate to produce the two sampled signals each with different samples at the symbol rate, providing a total of four sampled signals from the two antennas. These signals are linearly combined with respective weights to produce an output signal, the weights being determined to reduce co-channel interference with the desired signal represented by the output signal.
