然后求解这个加权矩阵方程，得到频率域的稀疏解。

Then the sparse solution in frequency domain can be obtained through computing the weighted matrix equation.

虽然稀疏解整体误差较小，但可能在一些点上的误差较大，为此提出对稀疏解的误差修正方法。

Although the over all error is small, errors of some points may be very big. The error correction of the sparse solution is also discussed.
