Triple-correlation direct sequence receiver
Brian M. Sadler · 2002
A self-referencing direct sequence spread spectrum receiver is presented which is based on an appropriate single lag of the auto-triple-correlation. The receiver is self-acquiring, in the sense that no local reference code is necessary. The received signal is auto-triple-correlated at a particular lag such that the transmitted code acts as its own reference. The proposed receiver is characterized by a bound on its probability of bit error in additive white Gaussian noise, and compared with a conventional coherent BPSK receiver.>
