    摘要： A method of transmitting and merging data is adapted to a sender and a receiver that are in communication with each other. The method comprises a sending stage and a receiving stage. The sending stage comprises: transmitting a first block data, a second block data and a third block data to the receiver by the sender; obtaining a fourth block data and a fifth block data by the sender; and transmitting the third, fourth and fifth block data to the receiver by the sender. The receiving stage comprises: receiving the first, second, and third block data by the receiver; merging the first, second and third block data to perform a convolution operation by the receiver; receiving the third, fourth and fifth block data by the sender; and merging the third, fourth and fifth block data to perform another convolution operation.

    摘要： A method for use in a wireless transmitter of interleaving coded bits includes: determining an integer number (M) of polar coded bits {e(0), . . . , e(M−1)} for wireless transmission; determining a smallest integer number (T) such that T(T+1)/2>=M; and determining a one-dimensional interleaving index array, interleavingId( ), that represents the column by column non-zero elements of a two-dimensional matrix. The two-dimensional matrix includes a hypothetical T by T matrix containing the polar coded bits {e(0), . . . , e(M−1)} input row by row without using the lower right corner elements of the T×T matrix. The method further includes: interleaving the polar coded bits {e(0), . . . , e(M−1)} using the one-dimensional interleaving index array resulting in the output sequence {f(0), . . . , f(M−1)} wherein f(i)=e(interleavingId(i)); and transmitting the interleaved polar coded bits to a wireless receiver.

    摘要： A method of operating a radio transmitter configured to transmit at least one sequence of logic values by transmitting transmission signals selected in a constellation diagram having a certain cardinality comprises selecting said transmission signals out of a first subset of transmission signals in said constellation diagram, said first subset comprising a first number of transmission signals, and a second subset of transmission signals in said constellation diagram, said second subset comprising a second number of transmission signals, wherein. The transmission signals in the second subset of transmission signals have an energy higher than the transmission signals in the first subset of transmission signals. The sum of said first number of transmission signals and said second number of transmission signals is less than said cardinality.

    摘要： The present disclosure describes aspects of a conductive receptacle collar for desense mitigation. In aspects, an apparatus comprises a printed circuit board assembly (PCBA) that includes an integrated circuit with signal lines for a wired data interface. The apparatus also includes a coupling component with a receptacle for the wired data interface and an enclosure in which the PCBA is mounted. The enclosure has an opening through which the receptacle for the wired data interface is exposed. A conductive collar is disposed between an exterior surface of the receptacle and an interior surface of this opening. The conductive collar contacts the receptacle's exterior surface and the interior surface of the opening to electrically couple these respective surfaces. By so doing, the conductive collar improves grounding of the receptacle to the enclosure, which may mitigate the desense of the apparatus's wireless receivers caused by operation of the wired data interface.

    摘要： A method of transmitting distributed data over a channel includes distributing data from a data source to N number of collaborating transmitter devices operable to synchronously transmit N number of contributing data signals based on the data to a receiver over a channel. Channel state information of the channel between each transmitter device and the receiver is obtained. A spatial spectral weight (SSW) filter for each transmitter device based on the obtained channel state information is determined. The SSW filter associated with each transmitter device is applied to each contributing data signal transmitted from the associated transmitter device. The N number of contributing data signals filtered by the SSW filters are transmitted through the channel to the receiver, such that the contributing data signals are received at the receiver synchronously and in substantial phase alignment such that the contributing data signals coherently combine to form a coherently combined data signal.
