    摘要: A system for transmitting data over a MIMO channel has a transmitter and a receiver. In the transmitter, the input data is encoded over at least two pipes by a concatenation of at least two constituent signal-space encoders. Each constituent encoder is used to generate, in response to the input data, a sequence of symbols from a channel alphabet having at least one dimension. Each symbol of the channel alphabet includes at least one complex symbol having real and imaginary coordinates. The transmitter interleaves the coordinates of the sequence of channel alphabet symbols, and transmits (from at least two transmit antennas) the interleaved coordinates. Preferably, each constituent encoder maximizes a minimum coordinate-wise Hamming distance between members of all valid pairs of symbol sequences, maximizes a minimum Euclidean distance between members of all valid pairs of different codewords, and obeys an equal eigenvalue criterion.

    摘要: A network entity in a multi-transmit antenna system, such as a transmitting or receiving entity, includes a component such as a pre-coder or a receiver, and is configured for full-spatial-rate coding data. The network entity is capable of providing a full-spatial-rate codebook having been designed by selecting an underlying partial-spatial-rate codebook designed for a system configured for partial-spatial-rate coding data. The full-spatial-rate codebook can then be designed in a manner including defining the full-spatial-rate codewords based upon partial-spatial-rate codewords of the partial-spatial rate codebook and basis vectors of a null space of the respective partial-spatial-rate codewords in a multidimensional vector space. The network entity can also be capable of selecting codewords of the codebook in accordance with a sub-space tracking method whereby the codewords of the codebook can be selected in a manner that exploits correlations therebetween.

    摘要: A communications system includes a source, a destination, and multiple relays. In a first time period, the source emits a first transmission and a first relay retransmits a prior source transmission. Then, in a second, subsequent time period, the source node emits a second transmission and a second relay transmits the source transmission from the first time period. Optionally, the transmission from the second relay also includes the message from the first relay during the first time period. Similarly, in a third time period, the first relay transmits a message that includes the second relay's transmission and the second source transmission from the second time period. Alternatively, the source node transmit in a first frequency band, the first and second relays receive only in the first frequency band, and retransmit in a second frequency band, and the destination receives in both the first and second frequency bands.

    摘要: A process for forming a pouch having an evacuated headspace containing a flowable material is disclosed. The process includes the steps of: providing a continuous tube of flexible and sealable film; supplying the continuous tube with a predetermined amount of flowable material; pinching the continuous tube above a sealing region so as to form a pinched portion of the continuous tube; evacuating the headspace between the pinched portion and the predetermined amount of flowable material; and sealing the continuous tube at the sealing region to form a top seal of a previously formed pouch containing flowable material and a bottom seal of a next-to-be filled pouch. Also disclosed is a vertical form-fill-seal apparatus for forming a pouch containing a flowable material and having an evacuated headspace.

    摘要: Fast fading in cellular systems causes time variation of the Channel Impulse Response (CIR) resulting in significant performance degradation that is reduced by adding a pulse train to the transmitted data symbols and estimating the CIR by averaging the symbols as they vary from one OFDM symbol to another within the physical data frame (or packet).
