OUT-OF-BAND EMISSION CANCELLATION

摘要

A transmission signal pre-processing method and apparatus for out-of-band emission cancellation are disclosed. For each of N subchannels in a band weighting each of N subchannel symbols by a calculated value in the range from 0 to 1 is performed. Precoding said N weighted symbols, organised as an N×1 matrix, by multiplication by a unitary matrix is then performed.
