An enhanced statistical model for the dual polarised MIMO land mobile satellite channel

An enhanced channel model for the dual polarised multiple input, multiple output (MIMO) land mobile satellite (LMS) channel is presented. We pay attention to the dual polarisation and MIMO model parameters proposed in [1] and [2] and give particular consideration to four areas we consider requiring development. These include removing unwanted high frequency components introduced through filtering of the slow variations to impose temporal autocorrelation between samples, Doppler shaping of the fast variations, implementation of a smooth state transition process and finally, an interpolation process to sample the channel at the required symbol rate for transmission.
