    摘要： The present invention provides a unique feedback system in a wireless communication system wherein the transmission channel is always overloaded with data, which is configured and modulated at a select order of modulation. Based on the channel conditions, only a portion of the data can be successfully received. As such, the receiver will attempt to receive the data using demodulation techniques corresponding to the different levels of modulation used to encode the data transmitted. The receiver will determine the data that is recovered, or the highest order of modulation at which the data is recovered, and provide feedback to the transmitter. The transmitter will then retransmit the data that was not properly received. By overloading the channel at all times, the maximum amount of data capable of being transmitted over the channel is optimized without requiring or heavily relying on the receiver feeding back channel condition information to the transmitter.

    摘要： A multi-stage receiver and method for recovering a traffic signal embedded in at least one received signal. The multi-stage receiver includes a plurality of sequential detection stages for processing each received signal and providing successively better estimates of the traffic signal. The multi-stage receiver includes, for each received signal, a first processing stage and a second processing stage. The multi-stage receiver also includes a final processing stage connected to the second processing stages. Each first processing stage generates a first estimate of the traffic signal from the respective received signal and each second processing stage generates a set of energy values from the respective first estimate of the traffic signal and from the respective received signal. The final processing stage combines the set of energy values from each second processing stage and generates an improved estimate of the traffic signal. By employing multiple stages in the receiver, there is an improvement in successive estimates of the traffic signal.

    摘要： An encoder for a wideband CDMA communications system comprises an outer Reed-Solomon code encoder and an inner parallel concatenated convolutional code (PCCC) or turbo code encoder. An iterative PCCC decoder, for decoding the inner code, includes summing functions in forward and feedback paths for producing extrinsic information to enhance soft decoding decisions by first and second decoders in successive decoding iterations. An outer code decoder connected following the PCCC decoder also can provide serial feedback information for enhancing iterative decisions by the PCCC decoder.

    摘要： The present invention provides an integrated antenna and visual display apparatus, or one of an antenna apparatus and visual display apparatus which is integratable with the other. Apertures are formed in a visual display, such as an OLED display. The apertures when formed in a conductive layer operate as radiating bodies of an antenna array. A subset of sub-pixels of the visual display can be removed in line with the apertures. An optically transparent substrate is located over the visual display, and an array of further conductive elements, which may be optically transparent, is disposed on an exterior of this substrate. The further conductive elements operate to direct the antenna signals through the substrate, by coupling in an impedance-matched manner with the radiating apertures.

    摘要： A multi-beam transmission method is provided for transmitting using an N-beam transmitter to a receiver having K receive beams. In the transmitter, a non-linear encoder implemented by a machine learning block, and a linear encoder are trained using gradient descent back propagation that relies on feedback from the receiver. For each input to be transmitted the machine learning block is used to process the input to produce N/K sets of L outputs. The linear encoder is used to perform linear encoding on each set of L outputs to produce a respective set of K outputs so as to produce N/K sets of K encoded outputs overall and N encoded outputs overall. One of the N/K sets of K outputs from each set of K beams. In order to allow a generalization to different SNRs, and to allow for time varying channel conditions, the non-linear layers, implemented in the non-linear encoder, are responsible for extracting features and regenerating the features, while the linear layers implemented in the linear encoder, are responsible for more generalization.
