Abstract
Methods and apparatuses for performing synchronization in a receiver of an analog code division spreading system are described. The method includes outputting a sampling point alignment signal to apply first time delays to align encoder code signals with a sampling point of an ADC The ADC is used to obtain digital samples of the orthogonal code-encoded analog signal at the sampling point. The method also includes outputting a decoder code alignment signal to apply second time delays to align decoder code signals with the digital samples. The method also includes outputting an orthogonal code alignment signal to apply third time delays to the decoder code signals and the encoder code signals, to maintain mutual orthogonality among the decoder code signals and to maintain mutual orthogonality among the encoder code signals.
