Embodiment Construction
[0036] Below in conjunction with accompanying drawing and example the present invention is described in detail as follows:
[0037] This embodiment provides a channel estimation method based on FDD massive MIMO Bayesian compressed sensing, specifically as follows:
[0038] Channel model:
[0039] Assuming that a base station with M antennas communicates with a single user, under frequency selective fading, the channel between the mth antenna of the base station and the user can be expressed as:
[0040] h m =[h m,1 , h m,2 ,...,h m,L ] T , m=1,2,...,M (1)
[0041] Among them, h m,l means h m In the lth multipath, L represents the channel length; due to the high resolution brought by the broadband system, L is usually larger, but due to the limited dispersion in the physical propagation environment, only a small number of multipaths are meaningful, The other channel coefficients are approximately 0; in other words, the channel vector It is generally sparse; moreover,...
