Abstract :
Discrete Fourier transforms (DFTs) may be used to create fixed orthogonal beams, and the receiver can then select the beam with the strongest desired signal to provide discrimination against interference. A more accurate method for locating the desired signal and its application in speeding up the adaptive convergence rate in a direct-sequence code division multiple access receiver are described
