Yanwen Wang · Modern Electronics Technique · 2010
The principle of precoding algorithm of the singular value decomposition(SVD),the geometric mean diameter decomposition(GMD) and uniform channel decomposition(UCD) algorithms for MIMO system are studied,and a detailed comparative study of these three algorithms are performed.According to the calculation of the bit error rate of SVD,GMD and UCD under the condition of different feedback noise errors,the influence of the feedback errors of the precoding matrix on the performance SVD,GMD and UCD can be observed.
