Abstract: Techniques are presented for receiving Quadrature Amplitude Modulated (QAM) symbols from a transmitter via a transmission path. In one example, a demodulator is configured to down-convert an incoming Radio Frequency (RF) signal to a baseband signal and convert the baseband signal to digital samples, and output the digital samples. A demapper is configured to receive the digital samples output from the demodulator and output data encoded in QAM symbols. The demapper is further configured to: determine from a constellation of QAM symbols a subset of QAM symbols that a digital sample from the demodulator may represent; apply an offset to each QAM symbol in the subset of QAM symbols of the constellation to result in a subset of offset QAM symbols; determine which QAM symbol in the subset of offset QAM symbols the digital sample most likely represents; and output data representing a determined QAM symbol.

Abstract: Systems and methods for managing interference in a communication network include transmitting a first downlink signal from a first transmit/receive point (TRP) to an electronic device using a beam. The electronic device can also receive a second downlink signal from a second TRP, where a portion of the first downlink signal from the first TRP interferes with the second downlink signal. The first TRP then receives a series of uplink pilot signals from the electronic device. Using the received uplink pilot signals, the first TRP can then estimate the angle of departure (AoD) for the intended signal (first downlink signal), and the AoD for the interference signal. The first TRP can then reconfigure the beam used to transmit the first downlink signal based on the estimated AoDs for the intended signal and interference signal to manage the interference effect that the first leakage signal has on the second downlink signal.

Abstract: Infrastructure electronics equipment incorporates infrastructure Local-Site Transports (LSTs). LSTs convey payload sampled signals over imperfect electromagnetic (EM) pathways whose physical properties are usually unknown when the equipment (e.g., Cameras, Displays, Set-Top Boxes) is manufactured. Prior LSTs hedge against EM pathway degradation in several ways: requiring high-quality cables (e.g., HDMI); restricting transmission distance, (e.g., HDMI); and/or reducing quality, via compression, to extend transmission distance somewhat (e.g., Ethernet). The subject of this disclosure is an infrastructure LST for sampled signals that causes the physical errors inevitably arising from propagation of sensory payloads over imperfect EM pathways to manifest in a perceptually benign manner, leveraging legacy infrastructure and reducing costs to achieve a favorable ratio of fidelity to transmission distance.
