It is well known that sequential decoding techniques such as Enhanced Maximum Likelihood Sequential Decoding (EMLSD) technique can obtain significant performance improvement over conventional decoding techniques in MultiCarrier Direct Sequence Code Division Multiple Access (MC-DS-CDMA) systems. Due to its simplicity and usefulness the EMLSD has received significant attention for several years. In this paper, three contributions are done for evaluation of the performance of the Multicarrier CDMA receiver. An expression is derived for Bit Error Rate (BER) with arbitrary spreading gain and Signal to Noise Ratio (SNR) requirements.
