    Abstract: An optical access network includes an optical hub having at least one processor, and a plurality of optical fiber strands. Each optical fiber strand has a first strand end connected to the optical hub. The network further includes a plurality of nodes connected to at least one segment of a first fiber strand of the plurality of optical fiber strands. Each node is sequentially disposed at respective locations along the first fiber strand at different differences from the optical hub, respectively. The network further includes a plurality of end-points. Each end-point includes a receiver. Each respective receiver (i) has a different optical signal-to-noise ratio (OSNR) from the other receivers, (ii) is operably coupled with at least one node of the plurality of nodes, and (iii) is configured to receive the same optical wavelength signal from the first fiber strand as received by the other receivers.

    Abstract: An optical network includes a transmitting portion configured to (i) encode an input digitized sequence of data samples into a quantized sequence of data samples having a first number of digits per sample, (ii) map the quantized sequence of data samples into a compressed sequence of data samples having a second number of digits per sample, the second number being lower than the first number, and (iii) modulate the compressed sequence of data samples and transmit the modulated sequence over a digital optical link. The optical network further includes a receiving portion configured to (i) receive and demodulate the modulated sequence from the digital optical link, (ii) map the demodulated sequence from the second number of digits per sample into a decompressed sequence having the first number of digits per sample, and (iii) decode the decompressed sequence.

    Abstract: A multiple access point system includes a wireless network including a first channel and a second channel. The system further includes a first access point and a second access point co-located within a single physical location environment, a wireless backhaul connecting the first and second access points to the wireless network, and a processor configured to (i) assign the first channel as a primary channel of the first access point and the second channel as a primary channel of the second access point, and (ii) assign the first channel as a secondary channel of the second access point and the second channel as a secondary channel of the second access point. The primary channel of the first access point does not overlap with the primary channel of the second access point, and the secondary channel of the second access point overlaps with the first access point.

    Abstract: A digital receiver is configured to process a polarization multiplexed carrier from a communication network. The polarization multiplexed carrier includes a first polarization and a second polarization. The receiver includes a first lane for transporting a first input signal of the first polarization, a second lane for transporting a second input signal of the second polarization, a dynamic phase noise estimation unit disposed within the first lane and configured to determine a phase noise estimate of the first input signal, a first carrier phase recovery portion configured to remove carrier phase noise from the first polarization based on a combination of the first input signal and a function of the determined phase noise estimate, and a second carrier phase recovery portion configured to remove carrier phase noise from the second polarization based on a combination of the second input signal and the function of the determined phase noise estimate.

    Abstract: Systems and methods presented herein provide for increasing a contention window of a UE employing a LTE communications operating in a radio frequency (RF) band comprising a conflicting wireless technology. In one embodiment, an eNodeB receives a transport block of data from a user equipment (UE). The transport block includes a cyclic redundancy check (CRC). The eNodeB then determines a checksum of the transport block based on the CRC, fails the checksum, and transmits a non-acknowledgement (NACK) of the transport block to the UE based on the failed checksum. The UE, in response to the NACK, increases a contention window and re-transmits the transport block to the eNodeB.
