摘要: This letter explores the benefits of compensating for transmitter gain and phase imbalances in a receiver quadrature communication systems. It is assumed that are introduced at only. The Gram-Schmidt orthogonalization procedure used to compensate imbalances. Computer simulation has been performed study coherent differential QPSK system. found bit error rate performance improved significantly if imbalance compensated for. However, no improvement can be obtained
