在完成gps信号跟踪之后，进行接收机的位置解算。得到接收机的正确位置。(After the completion of gps signal tracking, the receiver of the positioning solution. Get the correct position of the receiver.)

Low-density parity-check (LDPC) codes have recently emerged due to their excellent performance. However, the parity check (H) matrices of the previous works are not adequate for hardware implementation of encoders or decoders. This paper proposes a hybrid parity check matrix which is efficient in hardware implementation of both decoders and encoders. The hybrid H-matrices are constructed so that both the semi-random technique and the partly parallel structure can be applied to design encoders and decoders.
