Prototype AWA: design and implementation of a high speed ATM wireless access system using 25 GHz band

Error control for high-speed wireless ATM (WATM) operating at 20 Mbps or higher is an important research topics [l]. Automatic repeat request (ARQ) for WATM is required to achieve high throughput as well as high transmission quality, i.e., low CLR (cell loss ratio).Selective Repeat (SR) and Go-Back-N (GBN) are typical ARQ schemes [2]. Though SR-ARQ is superior to GBN-ARQ in terms of throughput performance, the implementation complexity of SR-ARQ's control procedures prohibits its application to high-speed wireless systems. GBN-ARQ, on the other hand, cannot avoid serious throughput degradation due to fairly high BER caused by multipath fading and shadowing..To solve this problem, this paper proposes a novel ARQ scheme named PRIME-ARQ (Partial selective Repeat superIMposEd on gbn ARQ). PRIME-ARQ achieves high throughput performance, almost equal to selective repeat ARQ, with a simple algorithm resulting in reduced implementation complexity for high speed operation. This paper describes the design, implementation, and performance of the proposed PRIME-ARQ. In addition, it shows the experimental results using a recently developed PRIME-ARQ processor.
