Abstract

The expansion of consumer and wireless devices has placed increasing demand on signal bandwidth. This increased demand on a finite resource is in turn driving interest in more efficient ways to use available bandwidth. One approach is through mixed modulation of existing waveforms to achieve complementary objectives. Historically, mixed modulated signals have been designed to include some degree of orthogonality between the different waveforms to preclude interference. Such approaches usually involve use of time division multiple access (TDMA) or code division multiple access (CDMA), or the use of orthogonal frequency division multiplexing. With the evolution of digital signal processing, another approach is mixed modulation through intended modulation on pulse (IMOP). In the past, IMOP was challenging due to both the obvious cross interference concerns and the limits of signal processing technology [1]. However, advances in both digital electronics and signal processing have opened the door to re-exploring IMOP approaches.
