Abstract

Compared with the traditional communication equipment, short wave communication equipment has strong anti-destroying ability. It can greatly reduce the complexity during the data transfer process. However, by the time-variation characteristic and the influence of the multipath interference, short wave communication system has some deficiencies in transmission. Therefore, it will be of great significance if we study the problems with great efforts and find a solution. The fountain code in the short wave broadband OFDM (Orthogonal Frequency Division Multiplexing) communication system will be introduced. And an excellent concatenated code composed of the Turbo and LDPC (Low Density Parity Check Code) codes will be used to run a pre-coding stage in this paper. The simulation results show that the concatenated codes are the mirror in the realization of long codes and hold the outstanding correction capability for random errors.
