METHOD FOR INCREASING SPECTRUM EFFICIENCY IN AN OFDM BASED MULTI-BANDWIDTH WIRELESS SYSTEM
摘要
A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.
