摘要：
We propose a flexible multi-frequency channel correlator upgrade for MUSER-I array. The upgrade correlator has a more flexible architecture to be extensible for signal receiving elements. It can process 1024 frequency channels in IF band and the correlation sensibility is improved by utilizing 4-bit quantization in pre-correlation as well. The enhanced multi-frequency channel processing capability also helps to implement RFI excision in the upgrade correlator.
