Abstract

This paper presents the analysis of digital single side band (DSSB) modulation technique with pilot symbol assisted modulation (PSAM). As a measure of the difficulty of linearization, the dynamic range, defined as the ratio of maximum to minimum instantaneous powers is commonly used. DSSB modulation is shown to provide the much reduced dynamic range from 5.5 dB to 8.9 dB whereas the dynamic range of QPSK is infinite and the dynamic range of OQPSK is around 11 dB. With DSSB, therefore, we can adopt more efficient amplifier with much simplified linearizer design. Besides, the proposed DSSB system does not need very sharp cutoff filtering and only sloped filtering, such as a raised cosine filtering, can be used
