ABSTRACT:
A DSSS receiver for processing a complex spread-spectrum signal which contains source information, the receiver including a despreading circuit which despreads a first complex signal that is derived from the spread-spectrum signal to produce a second complex signal; a differential demodulator which differentially demodulates the second complex signal to generate a third complex signal; and a sum and dump circuit which during each of successive symbol periods of the third complex signal sums multiple samples of the third complex signal to produce a fourth complex signal, wherein decision processing is performed in the fourth complex signal to extract the source information.
