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.

[ What is claimed is:] [1.]1. A method of correlation decoding spread spectrum CDMA signals in an order of decoding having a decoding sequence different from a reverse of a spread spectrum CDMA coding sequence of the transmitted signal, comprising:encoding with a spreading code signal prior to transmission with a sequential series of encoding steps F.sub.1 through F.sub.n ;transmitting the signal through a transmission channel;receiving the signal from the transmission channel;decoding the received signal by application of decoding steps of despreading codes with a sequential order different from a reverse order, F.sub.n through F.sub.1, of the sequential series of encoding steps F.sub.1 through F.sub.n.each encoding spreading code has a corresponding decoding despreading code andspreading and despreading codes are correlation related codes.
