Tight error bounds for asynchronous multicarrier CDMA and their application

Upper and lower bounds on the average bit error rate for binary phase-shift keying (BPSK), asynchronous multicarrier (MC)-CDMA communications using coherent detection are derived.

Beschreibung
Zusammenfassung:	Upper and lower bounds on the average bit error rate for binary phase-shift keying (BPSK), asynchronous multicarrier (MC)-CDMA communications using coherent detection are derived. The bounds can be made very tight by adjusting a parameter in the computation and this is demonstrated by numerical examples. Based on the derived bounds it is shown by numerical examples that the performance of asynchronous MC-CDMA using Zadoff-Chu sequences is better than that using Walsh codes.
