Abstract: A wireless communications transmitter is divided into N binary weighted communication signal processing paths including both fixed and variable gain communication signal processing chains. Specific bit sequences are used to select a combination of fixed and variable gain signal processing paths to adjust to a desired transmitter output power. Alternately, high and low power communication signal processing paths are chosen as needed with the high power communication signal processing path including an odd order harmonic notch filter.

Abstract: A technique to provide receiver processing of a plurality of component carrier signals that are received from one or more transmitting source by a terminal device, in which filtered component carrier signals are processed and aggregated in the terminal device. Two of the component carrier signals may be in a same frequency band grouping or two or more of the component carrier signals may be in a different band grouping. The receiver architecture allows for flexible processing of the component carrier signals by allocating the different bands into frequency band groupings to process the plurality of component carrier signals.
Abstract translation: 一种用于提供由终端设备从一个或多个发射源接收的多个分量载波信号的接收机处理的技术，其中在终端设备中对滤波分量载波信号进行处理和聚合。 分量载波信号中的两个可以处于相同的频带分组中，或者两个或更多个分量载波信号可以处于不同的频带分组中。 接收器架构允许通过将不同的频带分配到频带分组中以处理多个分量载波信号来灵活地处理分量载波信号。

Abstract: A single hybrid receiver is provided for processing both single carrier and carrier aggregated (CA) communications signals where carriers are split into independent receive paths without any additional external components. The receiver receives all contiguous and non-contiguous intra-band CA and inter-band CA signals allowing for improved rejection and balanced rejection of jamming signals on either side of the two carrier signals.
Abstract translation: 提供单个混合接收机用于处理单载波和载波聚合（CA）通信信号，其中载波被分成独立的接收路径而没有任何附加的外部分量。 接收机接收所有连续和不连续的带内CA和带间CA信号，允许在两个载波信号的任一侧改善抑制和平衡抑制干扰信号。
