Abstract:
The invention relates to a pulsed UWB receiver comprising an RF stage (501) followed by a baseband processing stage (502). The baseband processing stage comprises a Rake filter (550) having a plurality of fingers (551 1 , ..., 551K), each finger comprising an integrator for integrating the baseband signal during an acquisition window, a control module (580), and a detecting module (590) estimating the symbols received from the integration results. During a synchronisation phase, the control module (580) controls the respective positions of the acquisition windows associated with the different fingers, so as to scan at a reception interval, said RF stage operating, during this synchronisation phase, only during said acquisition plurality.
Abstract in simplified Chinese:本发明揭示使用一单一蜂巢式无线电来运行同时数据通信及语音通话监视。根据一些实施例,用户设备(UE)可经由该无线电而使用由一第一用户识别模块(SIM)支持之一第一无线电存取技术(RAT)来运行数据通信。该UE亦可经由该无线电而使用由一第二SIM支持之一第二RAT来运行用于一语音通信之传呼功能。在一些情境中,该第一RAT与该第二RAT相同。可使用共享实体层资源来同时地运行该数据通信及该等传呼功能。
