In the reverse link of DS/CDMA systems, the Peak-to-Average Ratio(PAR) performance can be analyzed by phase variations of spread signals. In the paper, we propose s PAR analysis method using phase variations of signals. Using this method, we analyze the PAR performances of existing spreading methods and suggest several methods improving the PAR performances. Also we show the proposed methods have negligible BER degradation compared to the existing ones.
