Kavitha, Veeraruna and Sharma, Vinod (2005) Comparison of Training, Blind and Semi Blind Equalizers in MIMO Fading Systems Using Capacity as Measure. In: IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005. Proceedings. (ICASSP '05), 18-23 March, USA, pp. 589-592.
Semi blind/blind equalizers are believed to work unsatisfactorily in fading MIMO channels compared to training based methods, due to slow convergence or high computational complexity. We revisit this issue. Defining a 'composite' channel for each equalizer, we compare the three algorithms based on the capacity of this channel. We show that, in a Rician (with line of sight, LOS) environment, semi blind/blind algorithms outperform training equalizers, but in Rayleigh channels, it is better to use training based methods. We also find the optimum training size in training and semi blind methods.
