Embodiment Construction
[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] For the basic MIMO system model such as figure 1 As shown, assuming that the number of transmitting antennas is N t , The number of receiving antennas is N R , Its channel is a flat fading channel, then the system can be shown by the following formula:
[0033] y=H·s+n (1)
[0034] Where y is N R ×1 received signal vector, s is N t ×1 transmit signal vector, n is N R ×1 noise vector, its mean value is 0, variance is N 0 / 2, H is N R ×N t One-dimensional channel model vector (channel matrix).
[0035] Using the maximum likelihood estimation algorithm, the expression is as follows:
[0036] min s ∈ Ω | | n ...
