Noise and ACPR correlation in CDMA power amplifiers

摘要

The issue of noise is one of the most important parameters when considering overall communication system quality. For wireless systems, major noise sources are the transmitter, the air interface and receiver noise. In code-division multiple access (CDMA) systems, the signal-to-noise ratio determines the bit error rate (BER) or frame error rate (FER) numbers that represent a digital information loss. In transmitters, one of the critical noise sources is a power amplifier (PA).
