Abstract :
In this paper, a novel scheme for achieving fast synchronization in interleave division multiple access (IDMA), called spreading-IDMA (S-IDMA), is investigated. By introducing an extra despreader after the interleaver, S-IDMA can exploit the advanced techniques from code division multiple access (CDMA) and derives signal to interference-plus-noise ratio (SINR) improvement before iteration detection process through correlation operation. Both theoretical analysis and simulation are carried out for evaluating the performance of S-IDMA in terms of signal to interference-plus-noise, bit error rate (BER) and complexity. It is indicated that S-IDMA can achieve fast synchronization with low computational complexity.
