摘要： A transmitter adjusts a transmitted power level by modifying a control input of a variable gain amplifier. A power amplifier control system includes an envelope extractor, an error extractor, and a feed-forward multiplier. The envelope extractor receives data signal inputs and computes the envelope of the combined signal. The error extractor generates an error signal as a function of the combined signal and the output power generated by the power amplifier. The feed-forward multiplier generates a modified error signal that is responsive to a function of the gain in a feedback path. A corresponding method for controlling a power level is also disclosed. In some embodiments, a transmit chain with a power control loop is used to adjust the transmit signal power applied at an input of a variable gain amplifier. A corresponding method for adjusting the transmit signal power level is also included.

摘要： A transmit signal second-order inter-modulation (IM2) canceller for a portable handset using a full duplex mode of operation (e.g., WCDMA) is used to controllably reduce IM2 introduced by a transmit signal that appears in a received signal in a receive channel of the portable handset. The transmit signal IM2 canceller includes a delay estimator and a digital signal adjuster. The delay estimator receives a first input from a receive channel and a second input from a transmit channel. The delay estimator generates an estimate of the IM2 that the transmit channel introduces in the receive channel. The digital signal adjuster removes the estimate of the IM2 before forwarding a modified receive channel signal to a baseband subsystem of the portable handset.

摘要： A digital modulator for a portable handset using 8PSK or EDGE modulation with a direct launch transmitter is used to controllably adjust the transmit power of the portable handset. The digital modulator includes a controller coupled between a memory and an accumulator. The controller is responsive to an indication that the transmit power should be transitioned. The controller temporarily alters the data transferred from the memory to the accumulator during transitions of the transmit power level.

摘要： A method and system for dynamically shifting spurious tones away from the desired frequency in a virtual local oscillator receiver, such that any undesired signal residing at such spurious tones are effectively delineated from the desired signal and removed from the RF input signal. The system detects the presence of potential undesired blocker signals in the RF input signal, and initiates an iterative power comparison and mixer signal adjustment loop. As the virtual local oscillator uses two mixer signals, the frequency of one of the mixer signals is adjusted during the loop until the power of the down-converted signal is minimized to a predetermined level. Minimized power in the down-converted signal is indicative of the absence of the blocker signal, since the presence of a relatively high power signal is indicative of a blocker signal overlapping with a desired signal.
摘要翻译：一种用于在虚拟本地振荡器接收机中动态地将杂散音调从期望频率移位的方法和系统，使得驻留在这种假音调处的任何不需要的信号被有效地从期望的信号中描绘出并从RF输入信号中去除。该系统检测RF输入信号中存在潜在的不希望的阻塞信号，并启动迭代功率比较和混频信号调节环路。由于虚拟本地振荡器使用两个混频器信号，所以在环路中调整混频信号之一的频率，直到下变频信号的功率被最小化到预定的电平。下变频信号中的最小化功率表示不存在阻塞信号，因为相对高功率信号的存在表示阻塞信号与期望信号重叠。
