摘　　要：文中提出一种新的卫星传输方式,即并行多路单载波方式(PMCPC)。PMCPC传输方式在提高频谱利用率的同时,大大提高了信号的抗截获能力。文中针对两路并行传输的情况提出了一种迭代译码算法,并对其性能进行了计算机仿真。A method of satellite communication named parallel-multiple-channel-per-carrier is proposed. The new scheme provides high spectrum efficiency and contributes a lot to the signal anti-interception performance at the same time. An iterative decoding algorithm suited for parallel-two-channel-per-carrier system is also presented and its performance simulated.
