摘要： A radio frequency receiver includes a receiver circuit for processing RF signals, an antenna to receive millimeter wave RF signals, and an attenuator circuit, coupled between the receiver circuit and antenna. In one embodiment, the attenuator circuit may be used to determine a signal strength of the millimeter wave RF signals, compare this signal strength to a first threshold value. If the signal strength is above the first threshold value, a level of attenuation applied to the millimeter wave RF signals may then be increased.

摘要： Techniques for sending and receiving signals include pre-distorting signals before transmission across a communication path. The signals are pre-distorted as a function of a distortion on the communication path. In one embodiments, transmitter a broadcasts to receiver b and there is also a transmitter b broadcasting to receiver a. This return channel enables both transmitters a and b to have a priori information regarding the transmission medium and path the signal takes. In this way, the nature of the distortion or interference is known to the transmitter, therefore, it pre-distorts the transmitted signal to compensate for the receiver exceeding its capabilities in recovering signal.
摘要翻译：用于发送和接收信号的技术包括在通过通信路径传输之前的预失真信号。信号作为通信路径上的失真的函数被预失真。在一个实施例中，发射机a广播到接收机b，还有一个发射机b广播到接收机a。这个返回信道使得发射机a和b能够具有关于传输介质和信号所采用的路径的先验信息。以这种方式，发射机已知失真或干扰的性质，因此，它预先歪曲传输的信号，以补偿接收机超过恢复信号的能力。

摘要： A digital data signal, such as a digital video signal, is intentionally pre-distorted before being sent over a network. In one embodiment, this pre-distortion may be performed in accordance with a pre-distortion pattern or algorithm which is shared with only intended receivers. The pre-distortion pattern may be used to vary the pre-distortion on a periodic basis, as frequently as on a symbol-by-symbol basis. The pre-distortion function may include distorting the phase and/or the amplitude of the digital signal's modulation.

摘要： The frequency of a digital data signal, such as a digital video signal, is intentionally varied or hopped before being sent over a network. This frequency hopping may be performed in accordance with a frequency hopping pattern shared with only intended receivers. The digital data signal may be further intentionally pre-distorted in accordance with a pre-distortion pattern which is also shared with only intended receivers. The frequency hopping and/or the pre-distortion patterns may be used to vary the frequency and modulation, respectively, on a periodic basis, such as a symbol-by-symbol or packet-by-packet basis.

摘要： A quantized channel rate and corresponding rate multiplier is determined on a transmitter-side of a communication system based on a measured minimum required bandwidth. In certain embodiments, the quantized data rate may be an integer multiple of the system's reference clock. The determined rate multiplier is then transmitted to the receiver-side at a default data rate prior to or near the beginning of a data transmission session, such as upon initialization. Prior to transmission, the data stream may be padded with some determined amount of null data such that the actual transmitted data rate is approximately equal to the quantized channel rate, and the receiver-side can readily recover the data clock using its known reference clock and the previously-provided rate multiplier.
