RECEIVER, TRANSMITTER AND VARIABLE BANDWIDTH TRANSMISSION METHOD

摘要

Solutions for receiving and transmitting variable transmission bandwidth signal are provided. A receiver comprises square-root raised cosine filter bank, each filter of the filter bank configured to filter a subband, and an adder configured to add up the output signals of one or more filters of the filter bank to obtain a sum signal, the sum of the subbands of the one or more filters being equal to the transmission bandwidth of the received signal. A transmitter comprises a transmission filter, the roll-off factor of the transmission filter being selected on the basis of the bandwidth of the signal to be transmitted.
