| 摘 要： | IntroductionThe consistency of amplitude and phase be-tween the two orthogonal outputs will be improvedconsiderably by adopting the LIF digital receiverwith parallel processing design1,2 ] .Meanwhile,LIF digital processing leads to a low amount of re-al- time data processing.As a result,a multi- chan-nel LIF digital receiver can be implemented usingtime division multiplex and a parallel processingarray( constructed by high speed DSP chips) ,suchas Sharc 2 1 0 6x and TMS32 0 C6x,and thu…

Normalized Design of Multi-channel LIF Digital Receiver |
| |
| Abstract: | A design method for parallel processing application on multi-channel low-intermediate-frequency(LIF) digital receiver was presented. 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. Using this method, the design of multi-channel digital receiver may be simplified. Finally, a design example was used to show how to apply this method. |
