Low latency Interleave Division Multiple Access System
説明
In this paper, we propose a novel architecture for IDMA system with low latency and high throughput for the uplink multi-user wireless system. The throughput of the proposed IDMA system can be improved to about double compared to the conventional IDMA system while the hardware complexity remains unchanged. To achieve this, the proposed system utilizes the interleaver/de-interleaver-less architecture to minimize the latency of the interference canceller in IDMA receiver. In the conventional architecture, the IDMA receiver sequentially processes the de-interleaving, interleaving, de-spreading and spreading that cause high latency. The proposed architecture can perform these sequential processes at the same time resulting in a reduction of interference cancellation operation cycles in half.
