Abstract : 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.
