Abstract:
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, said method 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 sequence other than that of the sequential series of encoding steps;each encoding spreading code has a corresponding decoding despreading code;spreading and despreading codes are correlation related codes;decoding the received signal is partial; andsuch decoding is distributed among several intermediate receiving stations located between an origin and a termination.
