  • A high-speed data transmission system (Overlapped Time Division Multiplexing System, OvTDM) and its performace are researched in AWGN channel. Simultaneously, the channel coded OvTDM system is researched. The optimal algorithm, which is soft-in soft-out Maximum A Posteriori probability (MAP) iterative joined detection and decoding algorithm is proposed for the coded OvTDM system. Simulation results show that the BER performance of the OvTDM system is better than that of the conventional QAM system under the same spectral efficiency. For the channel coded OvTDM system, the MAP soft-in soft-out iterative algorithm fully utilizes the encoding constraints formed by the OvTDM and obtains the optimal performance.
