    摘要: A communication system is provided that includes a composite transfer module that receives an input signal and performs one or more selective operations defined by a first transfer function on the input signal. The composite transfer module outputs a first signal. A joint detection module receives the first signal and performs joint detection on the first signal. The joint detection module utilizes channel estimation information of the first transfer function so as to allow the joint detection module to perform joint detection with an oversampling rate of 2× or higher.
