function res = OGSBI(paras)
% res = OGSBI(paras)
%
% OGSBI(paras) performs DOA estimation using Sparse Bayesian Inference
%
% Input:
% paras.Y: M * T matrix sensor measurements at all snapshots
% paras.A: M * N matrix columns are the steering vectors for different directions
% paras.B: M * N matrix columns are derivatives of the steering vectors wrt. different directions
% paras.sigma2: initialization of noise variance
% paras.alpha: initialization of alpha
% paras.beta: initialization of beta
% paras.rho: rho
% paras.resolution: grid resolution for the directions
% paras.maxiter: maximum iteration
% paras.tol: stopping criterion
% paras.isKnownNoiseVar: true if known variance false if unknown
% paras.K: number of sources
%
% Output:
% res.mu: mean estimation
