摘要： A laser array optical coupling assembly may be used to couple a laser array to an arrayed waveguide grating (AWG), for example, in an optical transmitter in a wavelength division multiplexed (WDM) optical communication system. The laser array optical coupling assembly may include an optical fiber tip array with polished optical fiber tips providing a reduced mode field diameter to improve coupling efficiency with the laser array. The laser array optical coupling assembly may also include a direct coupling of the laser array to the AWG with modified AWG inputs reducing the mode field diameter to improve coupling efficiency with the laser array. The laser array optical coupling assembly may be used, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON) or in other transmitters or transceivers in a WDM system capable of transmitting and receiving optical signals on multiple channel wavelengths.

摘要： Channel state information in a multiple-input multiple-output (MIMO) pre-coding system is quantized onto a codebook, which comprises one or more unitary matrices, using a cost function. Voronoi regions are computed from the codebook. The codebook may be updated based on the computed Voronoi regions. The channel state information may comprise a matrix V. The cost function f(A) is defined by the following relationship: f ⁡ ( A ) = ( 1 N ⁢ ∑ j = 1 N ⁢  a jj  2 ) where A is a matrix of size N by N and aij is element (i,j) of matrix A. Voronoi regions may be generated from the codebook for the unitary matrices. A set of matrices based on the Voronoi regions and the unitary matrices may be generated. Updating the codebook may be achieved by modifying the set of matrices into a new set of unitary matrices, where the new set of unitary matrices become the codebook.

摘要： An optical transceiver may include an optical fiber coupling assembly for coupling optical fibers to transmitter and receiver sub-assemblies to increase the number of usable channel wavelengths by reducing an incident angle on a WDM filter without causing unwanted back reflection to a laser. In one example, the optical fiber coupling assembly may be used to increase the number of usable channel wavelengths between the L-band and the C-band. The optical transceiver may be used, for example, in an optical line terminal (OLT) and/or optical networking unit (ONU) in a wavelength division multiplexed (WDM) passive optical network (PON) capable of transmitting and receiving optical signals on multiple channel wavelengths.

摘要： Certain aspects of a method and system for processing signals in a communication system may include maximizing system capacity for a time division duplex (TDD) multiple-input multiple-output (MIMO) system, based on reducing a search range within which to find a group of signals having maximum channel gain. At least one of: a first signal for a first user and a second signal for a second user may be selected, which are both within the reduced search range, and which provides a maximum system capacity. The first signal for the first user may be selected from the reduced search range corresponding to a channel gain that is greater than a channel gain corresponding to a remaining portion of the reduced search range. The reduced search range may be generated by sorting a plurality of signals based on a channel gain corresponding to each of the plurality of signals.

摘要： In a laser package, a tilted laser causes laser light to be coupled into an optical fiber at an angle relative to a fiber axis of the optical fiber. The tilted laser emits laser light at an angle relative to a lens axis of a lens such that the lens directs and focuses the laser light at the angle relative to the fiber axis. Tilting the laser allows the laser light to be coupled into the optical fiber substantially parallel to or aligned with the core of the fiber while causing back reflection to be directed away from the laser, thereby improving coupling efficiency and minimizing feedback. The tilted laser may be coupled to an angle polished fiber, for example, in a laser package such as a TO can type laser package, a butterfly type laser package, or a TOSA type laser package.

摘要： A method and system for channel quantization for multiuser diversity are provided. A quantizer may utilize quantization levels determined based on an objective function J that corresponds to a performance metric for a finite-rate feedback multiuser downlink communication system. The quantization levels may be obtained based on the results of maximizing the objective function J by means of an optimization algorithm. The optimization algorithm may be a multivariate optimization algorithm that may be implemented utilizing an iterative approach. The quantizer may utilize the quantization levels to quantize channel state information (CSI) to achieve multiuser diversity in the finite-rate feedback multiuser system. The performance metric may be based on signal-to-noise ratio (SNR), bit error rate (BER), and/or system capacity. The quantization levels may be utilized in a multiuser system where distributed quantization is needed for optimal selection.

摘要： Preamble for use within single user, multiple user, multiple access, and/or MIMO wireless communications. A selected preamble type is employed for use in generating a signal to be transmitted from one communication device to at least one other communication device. Depending upon a desired operational mode, as few as one preamble type, or two or more preamble types may be associated with a given operational mode. When operating in accordance with a given operational mode, a preamble type is selected from available preamble types of an operational mode. A preferred implementation may include two respective preamble types such that one preamble type is used for single user (SU) operation with transmit beamforming weights applied at the beginning of the packet or for open loop SU transmissions only, while the other preamble type, having an multiple user (MU) characteristic, is used for both SU beamforming and MU operations.
