Firstly, 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 con
When using RDSS positioning under elevation constraints,traditional positioning accuracy estimation methods may not reflect the impact of satellite ranging error and elevation error on positioning per
Beidou RDSS(Radio Determination Satellite System) short message and inter-station measurement and data transmission system all belong to satellite retransmission channel. In order to solve the problem
