    • Data is received that has been transmitted via a combination of radio frequency signals using carrier aggregation, each radio frequency signal occupying a respective radio frequency band, the bands being arranged in two groups separated in frequency by a first frequency region, the first of the two groups occupying a wider frequency region than the second group. Inphase and quadrature components of the radio frequency signals are filtered using a first bandpass filter bandwidth to give first bandpass filtered components and filtered using a second bandpass filter bandwidth, different from the first bandpass filter bandwidth, to give second bandpass filtered components. A reconfigurable receiver is configurable to a first mode to receive the combination of radio frequency signals, and is also configurable to at least a second mode. At least one first filter is configured, in the first mode, to use a first bandpass filter bandwidth and, in the second mode, to use a lowpass filter bandwidth. At least one second filter is configured, in the first mode, to use a second bandpass filter bandwidth, different from the first bandpass filter bandwidth.
    • 接收已经通过使用载波聚合的射频信号的组合发送的数据,每个射频信号占据相应的无线电频带,频带被布置成两组,频率分为第一频率区域,第一个频率区域 占据比第二组更宽的频率区域的组。 使用第一带通滤波器带宽对射频信号的相位和正交分量进行滤波,以给出第一带通滤波分量,并使用不同于第一带通滤波器带宽的第二带通滤波器带宽进行滤波,以给出第二带通滤波分量。 可重构接收机可配置为第一模式以接收射频信号的组合,并且还可配置为至少第二模式。 至少一个第一滤波器被配置为在第一模式中使用第一带通滤波器带宽,并且在第二模式中,使用低通滤波器带宽。 在第一模式中,至少一个第二滤波器配置为使用与第一带通滤波器带宽不同的第二带通滤波器带宽。
