RS(23,17) decoder for UWB
This paper presents the Reed-Solomon (RS) decoder for multiband OFDM(MB-OFDM) ultra-wideband(UWB). In UWB system, RS (23,17) code is adopted. To achieve high throughput and small area, two iterative Modified Euclidean (ME) blocks are proposed to work by turns in this paper. The architectures of syndrome block, ME block, Chien search block, Forney block are presented later in detail. At last, this architecture was implemented with 0.18 mum standard CMOS technology and can achieve 2 Gbps throughput with the clock frequency of 250 MHz.
