Abstract

This paper provides an analysis of the impact of amplitude modulated blocking signals on receiver performance due to device nonlinearity. Using a standard polynomial model of nonlinearity, we derive limitations on the receiver SNR capabilities, depending on the blocking signal modulation statistical properties. The phenomena that we focus on are cross-modulation due to odd-order nonlinearity and amplitude demodulation due to even-order nonlinearity. The results are then detailed for two types of blocking signal modulations: GSM/EDGE modified 8PSK and UTRA/FDD uplink HPSK.
