Principle information detection method for receiver in DS-CDMA system

摘要

The method involves simultaneously transmitting time dependent information signals of several connections, over a frequency channel. The signals fed to the receiver (EE) are formed by folding the transmit signals with individual channel coefficients, representing the transmission channels, and the split code of individual connections. The received signals are converted into the baseband, while the receiver contains the split code of several connections. The information signals, related to the individual connections, are separated, while taking account of mutual interference between connections. Then the connection related signals are equalised.
