AbstractStructures for power-efficient systems, requiring the use of non-linear amplifiers and thus Mis-Matched filtering, are presented. These architectures allow for changeable amounts of power, bit rate, and modem selectable formats. The benefits include power/spectral efficiency, in addition to robust operation in mobile environments . Alternatives to matched filter receivers are addressed for power constrained systems associated with mobile systems in frequency selective channel environments. Two types of modulation format FQPSK and GMSK, with different mismatch filters at the receiver, are analyzed.
