Abstract
In this paper, we propose parallel Viterbi decoders applied to UWB(Ultra Wide Band). In consideration of power dissipation and ease of design, we design the architecture, using 132MHz clock instead of 528MHz clock in Baseband. Because Deinterleaver writes and reads the transmitted data per 6Ncbps(The number of coded bits per symbol). using the difference between the number of sampling clock per symbol and the number of coded bits per symbol, we reduce performance degradation of parallel Viterbi decoders. In comparison with using 528MHz clock, the result is little difference.
