摘要： A communication system (20) includes a base station (22) and a number of peak-managed user equipment apparatuses (26) that simultaneously transmit peak-reduced FDMA communication signals (128) to the base station (22). The communication system (20) exclusively assigns payload subcarriers (44) to the apparatuses (26) and assigns a few noise-bearing subcarriers (48) for common simultaneous use by all apparatuses (26). Each user equipment apparatus (26) includes a peak reduction section (92) that distorts an otherwise undistorted modulated communication signal (86) into a distorted, peak-reduced communication signal (128) by generating and adding peak-reduction noise (131) to the undistorted signal (86). The peak-reduction noise (131) is primarily mapped onto the noise-bearing subcarriers (48) without conforming to an in-band noise constraint and may be mapped onto the assigned payload subcarriers (44) to the extent permitted by an in-band noise constraint. The peak-reduction noise (131) is blocked in unassigned payload subcarriers (46).

摘要： A transmission method for transmitting a first modulated signal and a second modulated signal in the same frequency at the same time. Each signal has been modulated according to a different modulation scheme. The transmission method applies precoding on both signals using a fixed precoding matrix, applies different power change to each signal, and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.

摘要： An example transmitter includes first and second circuit stages and interface circuits. The first circuit stage is configured to generate modulated signals each having a different carrier frequency from baseband signals. The second circuit stage is configured to generate radio frequency (RF) energy to be radiated by antenna(s). The interface circuits are coupled between the first circuit stage and the second circuit stage. The second circuit stage and the interface circuits are configurable to provide a first mode and a second mode. In the first mode, the second circuit stage provides transmit paths and the interface circuits couple each of the modulated signals to a respective one of the transmit paths. In the second mode, the second circuit stage provides a first transmit path and the interface circuits couple a sum of at least two of the modulated signals to the first transmit path.

摘要： This disclosure describes systems, methods, computer readable media, and/or apparatus related to encoding wireless communication preamble structures with cyclic redundancy check (CRC) that is performed on both a common part, as well as, station specific parts of a signaling field. The signaling field generated by this mechanism may be relatively shorter, resulting in less preamble overhead, than if a separate CRC was to be provided for each of the station specific parts, as well as the common part of the signaling field. In additional embodiments, tail bits may be provided for a combination of the common part of the signaling field and each station specific part of the signaling field. Compared to providing tail bits separately for the common part and each of the station specific parts, removing the tail bits from the common part may result in relatively less overhead of the preamble structure.

摘要： Various examples are provided for OOB interference and/or PAPR reduction in OFDM systems. In one example, a method includes generating a suppressing signal using channel state information (CSI) of a communication channel, where the length of the suppressing signal equals that of the OFDM symbol including a cyclic prefix (CP) and data portion; combining the OFDM symbol and the suppressing signal to generate a transmission signal, where the length of the suppressing signal is aligned with the length of the OFDM symbol; and communicating the transmission signal via the communication channel, which reduces and substantially aligns the length of the suppressing signal with a length of the CP at a receiving device. The CP and suppressing signal can be removed from the transmitted signal at the receiver using a CP removal matrix. In another example, a transmitting device includes OFDM encoding, signal suppression, combining circuitry to generate the transmission signal.
