The simulation result shows that : the performance of the proposed scheme is improved with comparison to pccc and sccc on both awgn channel and the rayleigh fading channel . in awgn channel , it is about same if the snr is low , if the snr is high , the improvement is 0 . 2 ~ 0 . 5db 结果表明：本方案的误码率性能与并行级联码和串性行级联码相比，在高斯白噪声信道上，低信噪比时几乎相同，高信噪比时有0 . 2 0 . 5db的改善。

In this paper , through modeling and analyzing the non - continuities in the rf structures of twt , scattering parameter s11 is derived to represent the peak - peak values of the ripples of gain and phase - shift in traveling wave tubes , providing with some instructions for the controlling of the uniformity of gain and phase - shift in twts 本文通过对具有高频不连续性的行波管进行建模分析，用表征不连续性的反射系数的幅度给出了行波管增益和相移峰峰值的量级，对控制相位一致性行波管的不连续性提供了依据。
