Paper Abstract

This paper will investigate the bit error rate (BER) performance of coded and interleaved continuous phase modulation (CPM) waveforms on multipath channels. Coded and interleaved CPM waveforms offer some very attractive performance benefits since the CPM waveform can be viewed as rate 1 recursive inner code which can be concatenated with an outer convolutional code and when iteratively decoded, achieve performance close to the Shannon bound. This paper will begin with a brief overview of CPM waveforms. Then, an investigation into several features of CPM waveforms such as spectral characteristics, uncoded performance and iterative decoded performance will be provided. Following this, the optimum CPM demodulator for use on multipath channels will be described and its BER performance evaluated for a few multipath channels. This paper will conclude with a brief summary of the results.
