The ARTM Tier 1 waveforms include two versions of Feher patented QPSK (FQPSK-B and FQPSK-JR) and a version of shaped offset QPSK (SOQPSK-TG). In this paper we examine three common detector architectures for the ARTM Tier 1 modulations: a symbol-by-symbol detector, a cross correlated trellis coded modulation (XTCQM) detector, and a continuous phase modulation (CPM) detector. We show that when us...

The effects of performing channel estimation in AWGN and Rayleigh channels using non-ideal interpolating and decimating filters on an OFDM system are investigated. Pilots are used to estimate the combined response of the channel and the filters. By making use of standard Gaussian approximation to the interference for the AWGN channel, we illustrate how to estimate the symbol error rate of a M-Q...

The packet error rate (PER) is a metric of choice to compute the practical performance of communication systems experiencing block fading, e.g., fading processes whose coherence time is relatively slow when compared to the symbol transmission rate. For these types of channels, we derive a closed-form asymptotic expression which approximates the value of the PER for high signal-to-noise ratio (S...
