Abstract :
In this paper we investigate the degradation in FEC performance of LTE and WiMAX air-interfaces in satellite mobile channels due to lack of sufficient time diversity caused by the use of a short transmit time interval (TTI). We then propose a generalized `split multicode transmission´ technique to overcome this problem without any reduction in the achievable user data rate. Simulation results are presented using the MAESTRO satellite wideband channel for rural areas.
