Abstract: An OFDM signal may include a first edge band signal corresponding to a first edge band of the bandwidth of the OFDM signal, a second edge band signal corresponding to a second edge band of the bandwidth, and a center band signal corresponding to a center band of the bandwidth. The OFDM signal may be filtered by filtering the first edge band signal and/or the second edge band signal, so that out-of-band radiation of the OFDM may be reduced or eliminated.

Abstract: A method of designing a truncated filter includes designing a prototype filter with a target frequency response, and selecting a soft truncation function with a roll-off parameter specifying a rate in which the soft truncation function transitions to zero. The method also includes applying the soft truncation function to the prototype filter to produce a truncated filter, and storing the truncated filter to a memory.

Abstract: System and method embodiments are provided for channel sounding in a frequency division duplex (FDD) system. The embodiments enable a transmission point (TP) to determine channel information about a downlink channel from an uplink channel sounding signal received on the downlink channel frequency band during a time window reserved for uplink channel sounding on the downlink channel frequency band. In an embodiment, a method in a controller includes determining with the controller a schedule for an uplink sounding window in a downlink frequency band, wherein the uplink sounding window comprises a transmission window in at least a partial downlink frequency band that is reserved for uplink channel sounding, instructing a TP to signal the schedule to at least one wireless device in a coverage area of the TP, receiving a channel sounding signal in the downlink frequency band, and obtaining downlink channel state information from the channel sounding signal.
