    摘要: A receiver which suppresses inter-cluster multipath interference by processing an impulse channel response consisting of two multipath clusters, each cluster having groups of signals with multiple delays. In one embodiment, the receiver includes a single antenna and parallel-connected delay units used to align the groups of signals before being input into respective sliding window equalizers. The outputs of the equalizers are combined at chip level via a combiner which provides a single output. In another embodiment, a cluster multipath interference suppression (CMIS) circuit is incorporated into the receiver. The CMIS circuit includes a hard decision unit and a plurality of signal regeneration units to generate replicas of the multipath clusters. The replicas are subtracted from the respective outputs of the delay units and the results are input to the respective sliding window equalizers. In another embodiment, multiple antennas are used to receive and process the clusters.

    摘要: A composite, useful as a flexible circuit, includes at least a portion of an electrical conductor having a first surface opposite a second surface. A first homogeneous polymeric film contacts the first surface of at least a portion of the electrical conductor. A second homogeneous polymeric film contacts at least a portion of the first film and the second surface of the at least a portion of the electrical conductor. The first and second films infuse to form a continuous phase surrounding the at least a portion of an electrical conductor. A process for producing a flexible circuit including hermetic sealing by providing at least one electrically conductive trace having a first surface opposite a second surface. At least a portion of the first surface is attached to a first homogeneous polymeric film. A second homogeneous polymeric film is contacted with at least a portion of the first film and at least a portion of the second surface. Thereafter, application of pressure to the first and second films, for a time at a selected temperature, promotes polymer infusion to form a continuous phase surrounding at least a portion of an electrically conductive trace.

    摘要: Two network nodes may exchange messages through a relay using physical-layer network coding combined with forward error correction coding (FEC). The relay determines a prime field order based on the channel condition and communicates the field order to the network nodes. Each network node encodes an outgoing message with linear codes over a field such as finite field of the field order, and transmits a signal carrying the encoded outgoing message. The relay receives a composite signal carrying the summation of the messages from the two network nodes. The relay decodes the composite signal and extracts a composite message with linear codes over finite field of field order, and broadcasts a signal carrying the composite message. Each network node receives the signal from the relay and extracts the message intended for it using linear subtraction over finite field of field order.

    摘要: A two-way relay wireless communication method and device may combine multiple bit steams, for one source node and two target nodes, and broadcasting a network coded combined bit sequence to reduce the number of time slots for transmission. A first device may receive a signal from the source node and a target node simultaneously in a time slot. The first device may receive subsequent signals from the source node and multiple target nodes simultaneously in successive time slots. Hierarchical modulation may be applied to the received signals. The first device may decode the received signals and generate a plurality of intermediate bit sequences (IBS)s for a broadcast transmission. The generated IBSs may be grouped according to a channel condition. A second device may be configured to receive the broadcast transmission and decode a portion of the broadcast transmission that is intended for the second device.
