摘要： A greater likelihood decoder, a method of deriving a reduced substreams maximum likelihood (RSML) decoded symbol vector and a multiple-input, multiple-output (MIMO) receiver incorporating the decoder or the method. In one embodiment, the decoder includes: (1) a suboptimal decoder that analyzes a received symbol vector to generate substream indicators and a decoded symbol vector estimate, (2) weakest substreams decision logic, coupled to the suboptimal decoder, that receives the substream indicators and selects weakest ones thereof and (3) subspace search logic, coupled to the suboptimal decoder and the weakest substreams decision logic, that further selects a reduced substreams maximum likelihood (RSML) decoded symbol vector from a subspace of decoded symbol vector candidates derived from the decoded symbol vector estimate and the weakest ones.

摘要： This invention relates to a continuous vacuum pan for use in the sugar processing industry, and more particularly but not exclusively, to a vertical, double calandria, continuous vacuum pan. The vacuum pan includes a vessel having a first enclosed chamber and a second enclosed chamber. A first heat exchanger is located in the first chamber, with a first vapour space defined in the first chamber above the first heat exchanger. A second heat exchanger located in the second chamber, with a second vapour space defined in the second chamber above the second heat exchanger. The first heat exchanger and the second heat exchanger both have heat transfer medium inlets, and the vacuum pan is characterized therein that the heat transfer medium inlet of the second heat exchanger is in flow communication with the first vapour space, in order for vapour contained in the first vapour space to be conveyed through the second heat exchanger as heat transfer medium.

摘要： A channel norm-based ordering and whitened decoding technique (lower complexity iterative decoder) for MIMO communication systems performs approximately the same level of performance as an iterative minimum mean squared error decoder. Decoding a signal vector comprises receiving a signal vector yk, multiplying the received signal vector yk by a conjugate transpose of a channel matrix H*. A column vector zk is generated. The entries of the column vector zk are reordered and an estimated channel matrix {tilde over (H)} is generated. The estimated channel matrix {tilde over (H)} decomposed using a Cholesky decomposition and generating a triangular matrix L. Triangular matrix L is solved backwards and a signal vector {tilde over (s)}k estimated. An estimate of the transmitted symbol vector Ŝk is generated.
