Abstract
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.
Claims16
A communication system comprising:
- a composite transfer module that receives an input signal and performs one or more selective operations based on a first transfer function of the input signal, the composite transfer module outputs a first signal;
- and
- a joint detection module that 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, wherein sampling frequency of the oversampling rate is at least equal to or higher than twice a frequency of a signal being sampled;
- wherein the joint detection module is configured to perform joint detection on more than 16 coded channels.
A method of performing joint detection in a communication system, the method comprising:
- receiving an input signal;
- performing one or more selective operations defined by a first transfer function on the input signal and outputting a first signal using a composite transfer function;
- and
- receiving the first signal and performs joint detection on the first signal using a joint detection module, 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, wherein sampling frequency of the oversampling rate is at least equal to or higher than twice a frequency of a signal being sampled;
- wherein the joint detection module is configured to perform joint detection on more than 16 coded channels.
