A Novel Intelligent Method for CFR Implemention in Transceivers for Multiple Scenarios

Transceiver is the core chip of 5G base station, among which Crest Factor Reduction (CFR) module is the most important digital function. In the design, it is compatible with performance and flexibility, adopts the way of Hardware-Software Co-Design, supports zero IF and low IF scenarios, supports peak search dynamic adjustment, develops parameter configuration platform to improve the efficiency of firmware configuration. The simulation and post-silicon test verify that the system has good performance and flexibility.
