Abstract :
We show that the performance of an interleave-division multiple-access (IDMA) system can be assessed by tracking the signal-to-noise-ratio (SNR) evolution of the iterative chip-by-chip (CBC) detection process. Based on this we develop a power allocation technique for performance optimization. Very high throughput (say 8 bits/chip) is observed for IDMA without sophisticated channel coding.
