BeiDou-1 Signal Simulation for Passive Location
2012As BeiDou-1 (BD-1) receivers are widely applied in communication, power and defense construction areas nowadays, the technology of assessing receivers based on simulators attracts more attention. However, due to the particular retransmission characteristics in BD-1 and the lagging research on relatively signal simulator, the simulator without ephemeris

Viterbi Decoder Design of Beidou RDSS Receiver
Applied Mechanics and Materials, 2013Firstly, the convolutional encoding with constraint length of 7 is used as the channel coding scheme in Beidou RDSS system. In addition, in receiver design Viterbi Decoder serves as the decoder of convolutional encoding. Finally, the optimized design of hardware construction in traditional Viterbi compared with that in decoder is introduced to reduce ...
