摘要：

Turbo code has the capability of error correction near Shannon's limit This code is concatenated of 2 recursive convolutional codes with pseudo random interleaving. In this paper secure turbo code performance in Rayleigh, Rician fading and NONGEO satellite channels are simulated and analyzed. Simulation results show that this code has appropriate performance in wireless channel in presence of light shadowing, and good performance in heavy shadowing. This scheme has the advantages of High-speed encryption and decryption with high security, smaller encoder and decoder size and greater efficiency.
