摘要: A system is described that consists of a variable modulation unicast system that utilizes multiple modulation schemes in a cable network for unicast applications and is capable of assigning users to different channels of differing modulation schemes in the network based on a feedback signal received in response to a transmitted probe signal. The system may also, in response to the feedback signal from a remote device in the network, assign a channel from a plurality of channels having differing carrier frequencies and modulation schemes to the remote device and may also modify the carrier frequencies of the channels.

摘要: Methods and systems for digitization of broadband analog signals may comprise in a radio frequency (RF) transceiver comprising a diplexer, first and second automatic gain and slope control (ASCS) modules, a combiner, and an analog to digital converter (ADC): receiving an input RF signal comprising at least two signals, splitting the input RF signal in the frequency domain into first and second signals of different frequency utilizing the diplexer, configuring a frequency-dependent gain level for each of the first and second signals utilizing the first and second ASCS modules, combining output signals from the first and second ASCS modules utilizing the combiner, and converting the combined output signals to a digital signal utilizing the ADC. The frequency dependent gain levels of the first and second signals may be configured to enable the ADC to operate with an effective number of bits (ENOB) of approximately 10.
