摘要：Current wireless communicatio n in real-life applications as well as reliable transmission of high data rate wireless communication model called OFDM requires communication systems for all kinds of orthogonal frequency division multiplexing is the base model (OFDM) multicarrier modulation technology that every si ngle low rate data stream containing divides the spectrum available in subcarriers with subcarrier is nothing but fur ther OFDM. Recently the Interleave-division multiple-access (IDMA) is presented scheme for multiple access. This approach employs the rando m interleaves as this is only way for user separation. But as compared to the CDMA, IDMA scheme based on number of distinguished features of CDMA b y overcoming the limitations of CDMA. Later this allo ws multi user detection (MUD) algorithm to use with multiple inputs and multiple outputs (MIMO) where numbers of users are more high-rate multiple access communication. The main aim of this paper is to present the review of OFDM model as well as an single user OFDM-IDMA model. OFDM-IDMA system is result of combination of advantages of both IDMA and OFDM.
