The report details the results of a study to evaluate and compare three candidate spread-spectrum waveforms for a combined communication and ranging system. These waveforms, specified for their low out-of-band interference characteristics, were minimum shift keying MSK, staggered quadraphase PSK SQPSK, and shapped biphase keying SBK. The study considers out-of-band interference characteristics, anti-jam performance, time of arrival accuracy and complexity of implementation.
