Error probability for coherent hybrid slow-frequency-hopped direct-sequence spread-spectrum multiple-access communications
Abstract
Performance analyses based on the average signal-to-noise ratio at the output of the receiver, and the average probability of error, are presented for an asynchronous hybrid slow-frequency-hopped/direct-sequence spread-spectrum multiple-access communications system which employs phase-shift-keying. Two distinct assignments of the signature sequences are examined: according to the first no two users use the same signature sequence, according to the second each sequence is assigned to a fixed number of users. Throughout the analysis arbitrary binary signature sequences and arbitrary frequency-hopping patterns are employed. The results are illustrated for specific m-sequences and Gold sequences, and random hopping patterns.
