Abstract: A receiver includes a radio frequency (RF) front end receives a received signal that is modulated via orthogonal frequency division multiplexing (OFDM) and generates a downconverted signal, based on the received signal. An OFDM demodulator generates subcarrier data based on the downconverted signal. The subcarrier data corresponds to a plurality of subcarriers. A subcarrier weighting module generates weighted subcarrier data by applying subcarrier weights to the subcarrier data corresponding to selected ones of the plurality of subcarriers. An OFDM decoder generates decoded OFDM data based on the weighted subcarrier data.

Abstract: A method and system is includes configurable carrier phase noise shaping. A fractional phase locked loop (PLL) uses a bank of delta-sigma modulators (DSM) to generate fractional ratios of the reference signal frequency. The bank of delta-sigma modulators provides for dynamic adjustments in the fractional PLL based phase noise performance of the communications network. The bank of DSMs is designed such that they have different and conflicting phase noise profiles. The communication network parameters are monitored and utilized for selecting a specific DSM from the bank of DSMs which most closely resembles a desired communications network phase noise profile.

Abstract: Embodiments of an apparatus and method for selective single-carrier (SC) equalization are provided. Multipath propagation in a communication channel often changes, and the severity of multipath propagation is often below worst case conditions supported by a SC communication device. When multipath propagation is less severe and below worst conditions, the use of frequency-domain equalization (FDE) in a SC receiver to mitigate ISI can be overkill and can result in excess power being consumed. The excess power consumption can be attributed to the general inability of the structure used to perform FDE to scale in terms of performance with channel conditions. Embodiments of the apparatus and method for performing selective equalization in a SC receiver allow either FDE or time-domain equalization (TDE) to be performed based on the current multipath propagation conditions of a communication channel. In general, TDE is used in place of FDE to conserve power when channel conditions permit.

Abstract translation: 提供了用于选择性单载波（SC）均衡的装置和方法的实施例。 通信信道中的多路径传播通常会发生变化，多径传播的严重程度通常低于SC通信设备支持的最差情况。 当多路径传播较不严格且低于最差条件时，在SC接收机中使用频域均衡（FDE）来减轻ISI可能会过度消耗，并可能导致多余的功耗被消耗。 多余的功耗可归因于用于执行FDE的结构在通道条件方面在性能方面的一般性不足。 用于在SC接收机中执行选择性均衡的装置和方法的实施例允许基于通信信道的当前多径传播条件来执行FDE或时域均衡（TDE）。 一般来说，当通道条件允许时，TDE用于代替FDE来节省电力。

Abstract: A configurable wireless communication device includes a baseband processing module, a transmitter section, a receiver section, an antenna, transmit/receive isolation circuits, high frequency switches, and a configuration module. The baseband processing module converts outbound data into an outbound symbol stream and converts an inbound symbol stream into inbound data. The transmitter section converts the outbound symbol stream into an outbound signal and the receiver section converts an inbound signal into the inbound symbol stream. The configuration module, in a power combining mode, couples, via a set of high frequency switches, the antenna to a set of transmit/receive isolation circuits, wherein a number of the transmit/receive isolation circuits in the set of transmit/receive isolation circuits is based on a desired combined transmit power.

The distributed antenna system includes antennas and an antenna coupling circuit. The antenna coupling circuit receives an outbound signal of a first wireless communication from a power amplifier and sends first and second components of the outbound signal to first and second antennas. The antenna coupling circuit also receives an inbound signal of a second wireless communication from a third antenna and sends the inbound signal to a low noise amplifier. The third antenna is a distance from the first antenna and from the second antenna such that, in air, the outbound signal is attenuated at the third antenna.
