Crypto-coding Technique for Land Mobile Satellite Channel

In this paper, we have introduced an improved combined cryptography-error correction method, which is called "Crypto-Coding". Although in previous experiments, combined error correction and encryption functionality has been studied into one single step, the modification needed in the introduction of encryption block improves the performance of the system. The combined System's performances are evaluated on Land Mobile Satellite (LMS) Channel. The results are compared with the system using ideal encryption and decryption.
