    Abstract: Technology is disclosed for an optical receiver. The optical receiver may include an optical and digital signal processing (ODSP) device. The ODSP device may include a photodiode operable to convert an optical signal to an electrical signal; a digital signal processor operable to generate a digital signal based on the electrical signal; a quantization component operable to generate a quantized output signal based on the digital signal; and a processing device. The processing device may be operable to measure one or more signal statistics of the digital signal; and identify one or more quantization thresholds, wherein the one or more quantization thresholds are computed based on the one or more signal statistics.

    Abstract: A system for a fiber-optic network includes a transceiver. The transceiver includes a fiber-optic interface unit and a host unit. The host unit includes a low-complexity error correction decoder and a high-complexity error correction decoder. One or both from the low-complexity error correction decoder and the high-complexity error correction decoder are selected to decode input data from the fiber-optic interface unit, the input data including codewords.

    Abstract: An apparatus for receiving a signal. The apparatus may include a demodulator configured to generate a binary signal from a received signal, a clock data recovery (CDR) circuitry configured to detect a phase error of the binary signal and generate CDR state information for the binary signal, a soft information generation circuitry configured to map the CDR state information to soft information for the binary signal, and a decoder configured to decode the binary signal using the soft information. The CDR circuitry may generate the CDR state information from multiple consecutive samples of the binary signal at least twice a symbol rate of the received signal. The soft information may be a log likelihood ratio of the binary signal, and the soft information generation circuitry may determine the log likelihood ratio based on an input bit error rate of the binary signal.

    Abstract: Technology is disclosed for an access point (AP) including a processing device and a transceiver. The processing device may receive, at the AP from a station (STA), information about an interference path between the STA and the AP; select, at the AP, a transmit power based on the information about the interference path between the STA and the AP; and determine, at the AP, a transmission type based on the transmit power, wherein the transmission type comprise one or more of a spatial reuse transmission or a spatial nulling transmission. The transceiver may transmit, from the AP to the STA, a transmission based on the transmission type.

    Abstract: A multi-carrier transmitter apparatus is disclosed. The apparatus includes an outer encoder, a shell mapper and an inner encoder. The outer encoder is configured to receive a signal, perform error correction using an outer code on the received signal and generate an outer encoder signal. The shell mapper is configured to perform constellation shaping on a subset of bits from the outer encoder signal and generate one or more constellation shaping bits. The inner encoder is configured to perform inner error correction/encoding using an inner code on a second subset of bits from the outer encoder signal and generate an inner correction signal.

    Abstract: A node circuit associated with a hybrid fiber coax (HFC) network is disclosed. The node circuit includes an optimizer circuit configured to process a plurality of signal-to-noise ratio (SNR) values associated with a plurality of subcarriers, respectively, associated with a set of cable modem (CM) circuits coupled to the node circuit. In some embodiments, at least one subcarrier is allocated to the set of CM circuits for communication with the node circuit. In some embodiments, the optimizer circuit is further configured to determine an optimal transmit power of the node circuit, based on the plurality of SNR values and a transmitter distortion of a transmitter circuit associated with the node circuit. In some embodiments, the transmitter distortion defines a transmitter distortion associated with the transmitter circuit in terms of a total transmit power of the node circuit.
