Abstract
Ultra-Wideband (UWB) is a technology for transmitting information spread over a large bandwidth. FCC (Federal Communications Commission) authorizes the unlicensed use of UWB in 3.1–10.6 GHz. Due to extremely low emission levels, UWB system tends to be short-range and indoors without huge signal interference to other communication systems. There are two techniques specified by IEEE 802.15.3a for Ultra Wideband system. In this thesis, the proposed UWB system employs orthogonal frequency division multiplexing. Viterbi Decoder is the channel decoder used for UWB system. To decrease the bit error rate with a noisy channel, channel encoding and decoding are used to protect the transmitted data bits. Viterbi Decoder is one of the decoders for convolutional encoder, and also the specified decoder for MB-UWB system. For ultra-wideband (UWB) communication systems, high-speed Viterbi Decoder is sufficient for its high data rates. In this thesis, multiple architecture systems, acquisition method, sliding block, and parallel method, are proposed for high-speed propose.
