Channel estimation error in space-time block coded system
Original language description
The purpose of this paper is present some numerical results of the concrete space-time block coded system with estimated CSI and compare the performance of a space-time coded system with perfect CSI (Channel State Information) and the same system with CSI estimated using Least Squares Method. Transmission over Multiple Input Multiple Output (MIMO) radio channels with rayleigh fading is considered. Further, the performance is investigated on non-orthogonal space-time code with double data rate using MIMOO system with two transmitting and two receiving antennas. Least Squares Method for MIMO channels estimation is described and its utilization for concrete non-orthogonal space-time block coded system is verified. Numerical results show the Bit Error Ratevs. signal-to-noise ratio for two estimation cases. First case assume lower and second case higher number of pilot symbols. The estimations are optimized for applied space-time code. Another numerical results show BER performance vs. numb

Chyba odhadu kanalů u systému s časoprostorovým kódováním
Czech description
Článek prezentuje numerické výsledky získané simulací rádiového systému s časoprostorovým blokovým kódováním, u něhž je odhad kanálové matice získáván metodou nejmenších čtverců. Numerickými výsledky jsou závislosti chybovostí systému při různých paramatrech odhadu.
