Description
Summary:We propose a time-frequency modulation and coding scheme for wireless communication in the presence of Linear Frequency Modulation (LFM) chirp radar interference. The time-frequency modulation framework used takes advantage of the structure of LFM chirp waveforms in time-frequency. The resulting modulation scheme results in a relatively small number of interference induced errors which can be corrected with a Reed-Solomon code. We present analytical and simulation results that show the efficacy of the approach. The resulting performance shows that LFM chirp interference can be effectively mitigated with a relatively small reduction in code rate.
