A Review on OFDM-IDMA Technique & its Implementation

Payal Sahu | Deepti Rai [9]

Abstract: It is difcult to analyze the performance of OFDM-CDMA systems. To accomplish this task, we need to characterize the correlation matrix among spreading sequences, because the system performance dependent on the choices of signature sequences. Al-though the performance is not sensitive to the choices of spreading sequences when long random spreading codes are employed, it is still mathematically demanding to evaluate the performance by large random matrix theory. OFDM-IDMA does not involve signature sequences, which greatly simplies the problem. This research paper reviews the basic ideas of OFDM-IDMA and several ways in which this concept has been implemented.
