摘要： A delay mismatched feed forward power amplifier is disclosed. Loop 1 includes a main amplifier (215) and is used to derive a carrier cancelled sample of the main amplifier output. Loop 2 includes an error amplifier (400) used to amplify the carrier cancelled signal derived from Loop 1 operation in order to cancel distortion products generated due to the nonlinear nature of the main amplifier. Loop 2 also utilizes a very short Loop 2 delay line (225). A significant efficiency gain is provided due to reduced output power losses associated with the Loop 2 delay line (225). Lower output losses also results in lower distortion levels produced by the main amplifier (215). This, in turn, reduces the size and performance requirements placed on the error amplifier (400). A smaller and more efficient error amplifier (400) is employed resulting in further amplifier system efficiency improvement. The delay mismatch is compensated by a third control loop, a special adaptive control algorithm or a combination thereof.
摘要翻译：公开了延迟失配的前馈功率放大器。环路1包括主放大器（215），并用于导出主放大器输出的载波消除采样。环路2包括用于放大从环路1操作导出的载波消除信号的误差放大器（400），以便消除由于主放大器的非线性特性而产生的失真产物。环路2还使用非常短的环路2延迟线（225）。由于与环路2延迟线（225）相关联的降低的输出功率损耗，提供了显着的效率增益。较低的输出损耗也导致主放大器（215）产生的较低的失真电平。这又降低了放置在误差放大器（400）上的尺寸和性能要求。使用更小且更有效的误差放大器（400），导致进一步的放大器系统效率提高。延迟失配由第三控制回路，特殊自适应控制算法或其组合补偿。

摘要： A system and method for distributing multiple wireless carriers to transmission sites is disclosed. Carrier precursors are distributed which are digital in format and compressed in bandwidth. The individual carrier precursors are combined using time division multiplexing to eliminate the need for excess bandwidth allotments. A separate time division multiplexed control channel is created to communicate carrier configuration and operating status information. With the carrier precursor data and configuration information, a software-defined radio is used to create actual carriers at or near the transmission location. Creating carriers at or near the transmission location provides the additional benefit of reducing transmission losses between the transmit antenna and the signal generating radio.

摘要： A feed forward power amplifier is disclosed which utilizes three signal cancellation loops. Loop 1 includes a main amplifier (215) and is used to derive a carrier cancelled sample of the main amplifier output. Loop 2 includes an error amplifier (400) used to amplify the carrier cancelled signal derived from Loop 1 operation in order to cancel distortion products generated due to the nonlinear nature of the main amplifier (215). Loop 2 also utilizes a very short Loop 2 delay line (225). A significant efficiency gain is provided due to reduced output power losses associated with the Loop 2 delay line (225). Lower output losses also results in lower distortion levels produced by the main amplifier (2.15). This, in turn, reduces the size and performance requirements placed on the error amplifier (400). A smaller and more efficient error amplifier (400) is employed resulting in further amplifier system efficiency improvement. A spurious signal detector (805) for out-of-band distortion detection and an associated microcontroller (810) for Loop 1 and Loop 2 control are also provided. A third signal cancellation loop is utilized to sample the amplifier output and reduce the carrier level of the signals sampled at the output of the amplifier before providing the sampled output to the spurious signal detector (805). By significantly reducing the carrier power level relative to distortion power levels a cost effective spurious signal detector (805) can be utilized. This also provides a faster conversion time in Loop 2 cancellation and enhanced cancellation of out-of-band distortion products due to a greater useful dynamic range available for the DSP (817) employed in the spurious signal detector (805).
