Abstract
In accord with the transmission system, encoded signals may be processed in intermediate stations and at receiving stations in an order different from the order of the original encoding process for transmission. In particular, the recovery of CDMA encoded signals does not require application of spreading/despreading codes in the original scheme or sequence of application of spreading codes. In one embodiment, code applications may be permuted without losing the original signal which has been encoded. In such applications, not all of the encoding spreading functions results in an increased spreading rate.
