Embodiment Construction
[0080] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0081] The mixed Gaussian noise sparse Bayesian spectrum sensing method of the present invention comprises the following steps:
[0082] 1) Construct a compressed spectrum sensing system model affected by mixed Gaussian noise;
[0083] 2) Explore the sparsity of the primary user power spectrum signal according to the compressed spectrum sensing system model;
[0084] 3) Using the sparsity of the primary user power spectrum signal to reconstruct the primary user power spectrum signal, and then judge whether the channel is occupied.
[0085] Since the geographic location of the primary user is unknown to the secondary user, in order to facilitate the secondary user to estimate the geographic location of the primary user, a virtual reference grid point scheme is introduced to transform a non-convex optimization problem into a convex optimization problem. ...
