Occupied bandwidth comparison of BBOST-CPM with two transmit antennas

Continuous phase modulation (CPM) has constant envelope and good spectral properties, so it is suitable for satellite communication systems which require high power amplifiers. On the other hand, recent broadband mobile communication systems use space time block codes (STBC) to achieve channel gain...

Description
Summary:	Continuous phase modulation (CPM) has constant envelope and good spectral properties, so it is suitable for satellite communication systems which require high power amplifiers. On the other hand, recent broadband mobile communication systems use space time block codes (STBC) to achieve channel gain by using multiple antennas. Burst based orthogonal space time-continuous phase modulation (BBOST-CPM) is a combination of orthogonal STBC and CPM which takes advantages of both merits. In this paper, we compare the occupied bandwidth of BBOST-CPM with two transmit antennas. We consider the relationship between modulation parameters and occupied bandwidth in detail. The results are useful for designing BBOST-CPM for future satellite communication systems.
