简介
In the field of communication, multimedia transmission is very important. Transmission of high quality images through wireless channel have always been challenging. This is due to the reserved bandwidth and capacity. So instead of conventional method of transmitting image with one carrier, the image signal is divided into subsets and different sub band carrier modulates each subset. So the main objective is to transmit an image in a multicarrier modulation system with good quality in a hostile radio channel. Multi carrier Code Division Multiple Access (MC-CDMA) is a multiple access scheme which combines both the benefits of orthogonal frequency division multiplexing (OFDM) and code division multiple access (CDMA). In the proposed MC-CDMA system, Discrete Cosine Transform (DCT) is used instead of Discrete Fourier Transform (DFT) because of its spectral energy compaction property. Further to …
