Parallel Processing Design of Multi-channel LIF Digital Receiver

This paper presents a design method for parallel multi-channel low-intermediate-frequency (LIF) digital receiver. It is based on the DSP sub-array with a simple topology and operation timing to evaluate and determine the processing capability and then construct the parallel processing array for multi-channel signals according to the restriction of operation timing. With this method the design of multi-channel digital receiver may be simplified. As an example, a design of shortwave band receiver is used to show how to apply this method.
