摘要： Self-jamming interference associated with a transmitted signal of an aggressor transmitter may affect a received signal of a victim receiver in a communication device. A victim receiver may obtain a non-linear interference cancelation (NLIC) signal from an aggressor transmitter of a communication device. The NLIC signal may be based, at least in part, on a source transmit signal that has been distorted by digital pre-distortion (DPD) at the transmitter. An NLIC unit may reconstruct a cancelation signal based on the NLIC signal. A receiver may remove the cancelation signal from a received signal.

摘要： A FM wireless headphone transmitter which uses a novel technique of varying the transmitted frequency. Instead of the traditional methods of using a variably meshing multi-plate capacitor, the invention uses a printed circuit inductance with a tuning plate attached permanently to the inside of the case so that frequencies are changes by changing cases. An alternative embodiment uses interchangeable tuning plates attached to the inside of the case by hook and loop pile type fastener material. The printed circuit inductance also serves as a transmitting antenna.

摘要： In conventional radio frequency (RF) systems, transmitters will usually convert baseband signals to RF so as to be transmitted. As part of the conversion process, the transmitters will perform digital predistortion (DPD), which uses feedback from a power amplifier. However, there are usually mismatches between the in-phase (I) and quadrature (Q) paths within with feedback loop. Traditional IQ correction filters were ineffective at providing adequate compensation for these mismatches, but here a filter is provided that provides adequate out-of-band compensation by use of frequency selectivity.
摘要翻译：在常规射频（RF）系统中，发射机通常将基带信号转换成RF以便被发送。作为转换过程的一部分，发射机将执行使用功率放大器反馈的数字预失真（DPD）。然而，通过反馈回路中的同相（I）和正交（Q）路径之间通常存在不匹配。传统的IQ校正滤波器在为这些不匹配提供足够的补偿方面无效，但是提供了一种通过使用频率选择性提供足够的带外补偿的滤波器。

摘要： Problems arising from a pre-emphasis filter, particularly an infinite-impulse-response filter, in a signal modulator are solved by detecting sequences of the same bit or symbol in a modulation signal and compensating the corresponding d.c. offset in the signal generated by the pre-emphasis filter without real-time feedback. The amount of offset compensation can be defined during design of the modulator or adjusted or calibrated during production. It is not necessary to change the transfer function of the pre-emphasis filter, but only to correct the d.c. offset of the filter output signal.

摘要： Self-jamming interference associated with a transmitted signal of an aggressor transmitter may affect a received signal of a victim receiver in a communication device. An aggressor transmitter may provide two or more non-linear interference cancelation (NLIC) signals, including a first NLIC signal and a second NLIC signal. A NLIC unit may reconstruct an interference signal based on a selected one of the first NLIC signal or second NLIC signal. Power of the transmitted signal at the aggressor transmitter may be used to select either the first interference cancelation signal or the second interference cancelation signal. The first and second NLIC signals may differ by the use of digital pre-distortion (DPD) at the aggressor transmitter.

摘要： An IQ modulator incorporates a quadrature network that is responsive to a frequency dependent control signal and that has in-phase and quadrature signals that are of equal amplitude and in exact quadrature over a wide range of applied frequencies. The quadrature network includes RC and CR phase shifters whose C's are fixed capacitors of equal value and whose R's are made equal to each other and to the capacitive reactance of the C's by the action of the frequency dependent control signal. The R's may be FET's. The frequency dependent control signal may be generated without express knowledge of the applied frequency by a servo loop that nulls out the amplitude difference between the in-phase and quadrature outputs from the quadrature network; it may also be generated from a look-up table as an express function of frequency. The frequency dependent control signal is split into separate instances that are applied to each R, and an offset may be introduced therebetween to provide extreme precision. The offset may be fixed or programmatically controlled as a function of frequency. Varactors may be used to provide variable C's in cooperation with fixed R's. The entire circuit may be fabricated as a GaAs IC for use in the frequency range of 200 MHz to 3 GHz.

摘要： A driver system with emphasis or de-emphasis control of optic signal generator comprising an input configured to receive an input signal that is to be transmitted as an optic signal. Also part of this system is a rising edge delay creating a first delay signal relative to the input signal and a falling edge delay creating a second delay signal relative to the input signal. A multiplexer receives the first delay signal and the second delay signal and selectively outputs either the first delay signal and the second delay signal to an amplifier. A first amplifier amplifies the input signal to create an amplified input and a second amplifier amplifies the multiplexer output signal to create a de-emphasis signal. A summing junction subtracts the de-emphasis signal from the amplified input to create a driver output signal. The rising and falling edge delays may each comprise two more delays.
