| Abstract: | A scheme of parallel multi-channel receiver is introduced.The scheme is based on the theory of multi-rate signal processing and the broadband band-pass sampling software radio architecture.It used TI′s digital up/down-converter GC5016 as the core chip of the receiver.The structure and function of GC5016 is introduced.The theoretical analysis and simulation research of CIC and PFIR used in re-sampling extraction and filter integral are proposed.CPLD as the main peripheral device generated configuration timing and completed reconfiguration under the control of the PC.The scheme has high integration,flexibility and wide range of application by using programmable devices extensively. |
