<p>In an HPSK modulating process of carrying different items of information on I- and Q-axes on an HPSK signal dot diagram, it is necessary to take into account another different dimension in addition to codes on the code domain. The present invention provides an improved method of displaying code domain power (CDP). After an IF signal produced by converting a frequency of a CDMA signal is IQ-demodulated, I and Q component signals are individually descrambled and despread as BPSK modulated signals. After CDPs are calculated from descrambled and despread signals, they are displayed as a CDP of an I-axis and a CDP of a Q-axis. By displaying the components on different axes as shown in FIG. 4, the power distributed on the I- and Q-axes and the relationship between the power and codes can quickly be recognized visually. <IMAGE></p> |
