摘要： A multi building block architecture may be configured to generate a waveform (a “target wideband signal”) for use in a wireless communication system, where the waveform supports a variety of baseband signals. The task of generating a target wideband signal can be divided into several tasks, each task relating to the generating of one of a plurality of sub-carrier bands. Each of the sub-carrier bands (sub-bands) may be generated by one of the sub-band building units included in the sub-band building blocks of the architecture. Several sub-bands may be formed, by a sub-band group building block, into a sub-band group. Multiple sub-band groups may be formed, by a wideband building block, into the target wideband signal.

摘要： A wireless communication system includes first and second transceivers operable to transmit and receive signals over a communication channel using a plurality of modulation modes. A first signal is received which has been transmitted using a first modulation mode over the communication channel from the first transceiver to the second transceiver, and a first channel equalisation characteristic for an equaliser of a first type for receiving the first signal at the second transceiver is determined from measurements of the communication channel. From the first channel equalisation characteristic, a second channel equalisation characteristic is determined for an equaliser of a second type for a second modulation mode. A measure of a difference between the second and the first channel equalisation characteristics is determined, and the second modulation mode is selected for transmission over the communication channel from the first transceiver at least in part in dependence on the measure.

摘要： 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.
摘要翻译：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。
