Abstract :
Generating signature sequences using operators of the discrete periodic wavelet transform is demonstrated. A new application of a fast optimal receiver algorithm for synchronous orthogonal code division multiple access augmented with time division multiple access (OCDMA/TDMA) is shown. Finally, a novel method to generate signature sequences with low residual noise using a cosine modulated filter bank (CMBF) structure is presented.
