Code Division Multiple Access (CDMA) is a commonly implemented wireless access technology which involves performing huge correlations in real-time, notably at the receiver. Most baseband receivers are thus integrated in hardware to match this prerequisite. At the same time, the wireless technologies
Currently, code-division multiple access (CDMA) technique continues to be a dominant air-interface technology for personal wireless communication systems. Mobile communication systems based on CDMA is always subject to multiple access interference (MAI) problem due to the difficulty in maintaining orthogonality of CDMA signals in a mobile environment.
From its beginning, transmit power has always placed a significant constraint on the performance of wireless radio systems. The transmit power control problem can be characterized as that of maintaining adequate power in each transmitted waveform so as to increase the expectation
