摘要: The invention provides a mixed precode design method for an actual broadband large-scale MIMO system. comprises the following steps: at radio frequency end, supposing analog precodes on all carriers to be equal, and calculating ideal matrix by taking maximizing system spectral efficiency as criterion utilizing integrated channel state information; according phase shifter characteristic of system, determining each carrier in reality, designing position correcting digital domain, deviation different reality approach precode, multiplying occurring obtain designed matrix; base band equivalent low-dimension information, obtained scheme.
