| Abstract: | A signal transmission scheme was proposed, which is suitable for Ka-band mobile satellite channel. The numerical simulation results provide dependable data for final implementation. Meanwhile, an iterative channel estimation algorithm, which can improve bit error rate (BER) performance of proposed Turbo coded GMSK signal transmission scheme dramatically, was expressed. |
