    摘要： Disclosed is a method for measuring the molecular rotation speed (the number of rotations or the rotation frequency) of a fullerene or a fullerene derivative in a relatively simple and inexpensive manner, for the evaluation of the fullerenes. The method comprises having a thin film of the fullerene or the fullerene derivative absorb an electromagnetic wave varied in frequency, and measuring the change in electromagnetic wave intensity against temperature, thereby determining the molecular rotation speed of the fullerene or the fullerene derivative from the frequency of the electromagnetic wave at the temperature where there is an abrupt change in the electromagnetic wave intensity from the absorption region to the non-absorption region. In a preferred embodiment, electromagnetic waves produced from the surface of a surface acoustic wave device are used.

    摘要： A communications system, comprising a transmitter and a receiver, are operable to communicate information using a spatial multiplexing method. The transmitter is operable to separate data to be transmitted into two categories, Alamouti encoding the symbols of the first category and transmitting them on an even number of antennae, and not encoding the second category of symbols, but merely using a modulation scheme such as QAM, and transmitting them on one or more further antennae. A corresponding receiver is operable to successively detect signal components received on corresponding spatially displaced antennae, and then to determine an estimated channel response from the signal components. A weighting function is then derived to extract a stream of data from the received signal, which, on the basis that the Alamouti STBC encoded signal will have the highest signal to noise ratio, will normally be the latter, while other data not encoded according to Alamouti is detected thereafter.

    摘要： According to one embodiment there is provided a method performed in a transmitter side of a multiuser minimum square error linear precoding MIMO system that comprises a transmitter with a plurality of transmit antennae and a plurality of receivers. Each receiver of the plurality of receivers comprises a plurality of receive antennae. The method is a method of scheduling receivers from among the plurality of receivers and comprises obtaining, for some or all of the receivers, receiver channel information that quantifies the properties of transmit channels between receiver antennae of the receiver and transmit antennae of the transmitter and establishing an order for determining the receiver combining vectors of the some or all of the receivers. The order is established by selecting as a next receiver in the order a so far unselected receiver from the some or all of the receivers that minimally increases the mean square data transmission error. The establishing of the order is based on the channel information of any receivers previously selected in the order and of unselected receivers.

    摘要： Code designs for channel coding with side information (CCSI) based on combined source-channel coding are disclosed. These code designs combine trellis-coded quantization (TCQ) with irregular repeat accumulate (IRA) codes. The EXIT chart technique is used for IRA channel code design (and especially for capacity-approaching IRA channel code design). We emphasize the role of strong source coding and endeavor to achieve as much granular gain as possible by using TCQ. These code designs synergistically combine TCQ with IRA codes. By bringing together TCQ and EXIT chart-based IRA code designs, we are able to approach the theoretical limit of dirty-paper coding.

    摘要： Codebook based communication of precoding data between two stations involves determining a ‘best fit’ precoding at a receiving station, on the basis of channel state measurements taken therein. The best fit precoding is compared with pre-agreed entries in a codebook, and an indicator is sent back to the terminal emitting the analysed signal. The determination is separated into two elements, one being sufficient for use with SU-MIMO, and another being provided, with a second codebook indicator, if MU-MIMO is to be employed. This second codebook indicator points to a codebook of eigenvector representations for the multi-user space in which the channel is persisting.
