A novel peak-windowing technique for WCDMA systems
In Wideband Code Division Multiple Access (WCDMA), the high crest factor (CF) in the downlink signal has imposed a tight requirement on the linearity characteristic of the transmitter power amplifiers (PAs). This paper proposes a new peak-windowing technique to reduce the CF of a WCDMA signal. Computer-simulation tests have been carried out to study the effects of the proposed technique on the downlink signal of a WCDMA system. Results have shown that the performance of the technique, in terms of reduction in the CF, the error-vector-magnitude (EVM), the peak-code-domain error (PCDE), the adjacent-channel-leakage power ratio (ACLR) and the bit-error rate (BER) performance, are superior to other clipping and/or windowing techniques studied in this paper. © 2006 IEEE.link_to_subscribed_fulltex
