Design and Simulation of Viterbi Decoder Used in Navigation Systems

We designed low power serial Viterbi decoder used in navigation systems.We introduce the whole architecture of the decoder and the design and features of each module in detail.The waveform shows that the designed Viterbi decoder can work in right condition and correct errors during transmission.The synthesize result under SMIC 0.18 μm technology shows that the area of the circuit is 4 102 gates, and the power is 399.514 μW.
