摘要： A method for selecting modulation and coding scheme (MCS) for multi-antenna systems comprises the steps of: a multi-antenna system transmits signals according to MCSs of single spatial stream and determines an MCS accordingly. Subsequently, the multi-antenna system increases the number of the spatial streams applied, transmits signals according to the corresponding MCSs and determines an MCS accordingly until an optimum MCS is found.

摘要： The module for switching between a long guard interval and a short guard interval comprises a signal processing unit, a measurement unit, a comparison unit and a switching unit. The module receives a first data symbol, and the data symbol has one of a long guard interval and a short guard interval. The signal processing unit is configured to generate a second data symbol in accordance with the first data symbol. The measurement unit is configured to measure a portion of the first and second data symbols in order to generate a first measurement value and a second measurement value. The comparison unit is configured to generate an output signal by comparing the first and second measurement values with a threshold value. The switching unit is configured to selectively switch guard intervals of subsequent data symbols in accordance with the output signal.
