| Abstract: | Several pilot-assisted frequency-domain channel estimation algorithms are proposed for distributed space-frequency coded cooperative communication system over frequency-selective fading channels,including least square(LS),linear minimum mean square error(LMMSE),and low-rank LMMSE estimation algorithm(Lr-LMMSE).The mean square error expressions of the proposed algorithms are also derived.Theoretical analysis and simulation results confirm the high practicality and accuracy of the proposed channel estimation ... |
