Performance Analysis on Interference and Frequency-to-Time Mapping Based Frequency Hopping Receiver

The receiving performance of a frequency hopping receiver based on interference and frequency-to-time mapping are analyzed. broadening the passband induced by high speed is theoretically spurious-free dynamic range (SFDR), frequency-dependent RF gain, average signal-to-noise ratio (SNR) corresponding to gain derived indicate performance. Experimental verifications SFDR were conducted. at 7.21 GHz 77.23 dBc, for passbands located from 7 23 GHz, variance below 3.2 dB, which fits well with simulated results difference less than 3.7 dB. 2.6 40.9 tested, 2 dB compared theoretical results.
