Abstract:

A new technique is proposed that offers significant reduction of multiple access interference (MAI) encountered in asynchronous multicarrier code division multiple access (MC-CD MA) detection. Using a dual frequency switching component at the transmitter enables the removal of a portion of unwanted interference signals from the decision variable. Biterror rate (BER) comparisons are shown for the use of both Gold and Walsh-Hadamard (WH) spreading sequences. The proposed switching technique clearly outperforms the existing MC-CDMA technique, however, additional bandwidth is required.
