- Abstract
The telecommunication market is reaching new types of customers who require their applications in transportation. The provision of cost-effective broadband multimedia services to mobile platforms (train, vessel, and aircraft) seems feasible only via a satellite system. Broadband satellite communication system for mobile platforms, especially in the land mobile satellite scenarios, subjects to hard propagation conditions such as high Doppler spread, shadowing, blockage, and non-negligible multipath fading. The mobility effects bring a challenge for equalization of broadband satellite channel. In this paper, mobile satellite downlink channel is modeled and a new efficient frequency-domain equalizer (FDE) based on block processing and soft interference cancellation is proposed. Computer simulations show that the novel FDE outperforms the conventional equalizers in both performance and complexity.
