High throughput and low power reed solomon decoder for ultra wide band

Abstract

Reed Solomon (RS) codes are widely used in a variety of communication systems. Continual demand for ever higher data rates makes it necessary to devise very high-speed implementations of RS decoders. In this chapter, a uniform comparison is drawn for various algorithms and architectures proposed in the literature, which help in selecting the appropriate architecture for the intended application. Dual-line architecture of modified Berlekamp Massey algorithm is chosen for Ultra Wide Band (UWB). Using 0.12 ìm technology the area of the design is 0.22 mm2 and throughput is 1.6 Gbps. The design dissipates only 14 mW of power in the worst case, including memory, when operating at 1.0 Gbps data rate. © 2006 Springer.
