Abstract : Adaptive transmission techniques, such as adaptive modulation and coding, adaptive power control, adaptive transmitter antenna diversity, etc., generally require precise channel estimation and feedback of channel state information (CSI). For fast vehicle speeds, reliable adaptive transmission also requires long-range prediction of future CSI. In this paper, we propose using past channel observations of one carrier to predict future CSI and perform adaptive modulation without feedback for another correlated carrier. We derive the minimum mean-square error (MMSE) long-range channel prediction. We use a standard stationary fading channel model (Jakes model) and a novel physical channel model to test our algorithm. Keywords—Slow Frequency Hopping, Channel State Information, Long Range Prediction, Adaptive Transmission, Partial- Band Interference, Diversity.
