    Abstract:

    Iterative detection for serially concatenated convolutional code with random symbol-wise interleaver and Multi-h Continuous Phase Modulation(Multi-h CPM) is proposed. The symbol-by-symbol Maximum A Posteriori(MAP) detector and its system parameters for Multi-h CPM are designed. A scheme of associated Singular Value Decomposition(SVD) with Frequency Pulse Truncation(FPT) is used for reducing the complexity of states trellis as well as the number of matched filters. The simulations of the 2nd new telemetry scheme(Tier2) show that the proposed system has the gain of 3.5 dB than the Low-Density Parity-Check(LDPC) code which has the same code length and code rate. By using the proposed scheme, the numbers of trellis states and matched filters are reduced to 64 and 2 respectively(from 256 and 64 respectively), however the performance loss compared with the optimum iterative detector is negligible.
