Abstract: A multi-user detector of transmitted signals includes a bank of despreaders and a processor. Each despread signal (produced by the despreaders) has cyclic and channel variations. The bank of despreaders despreads the transmitted signals to produce despreaded signals and the processor receives the despreaded signals and separately processes the cyclic and the channel variations. The processor includes a cyclic variation processor and a channel variation processor. The cyclic variation processor generally processes the cyclic variation of the transmitted signals and the channel variation processor communicates with the cyclic variation processor and processes at least the channel variation of the transmitted signals. The cyclic variation processor includes a weighting operator which weights the transmitted signals with at least one tap weight and a tap weight generator which generates the at least one tap weight at least from a cyclic code.

Abstract: A method includes receiving reference signals in a mobile communication terminal, which is designed to receive data-carrying signals that are transmitted from a base station using one of multiple predefined Modulation and Coding Schemes (MCSs). One or more pre-calculated mappings between Signal-to-Noise Ratio (SNR) and error rate for one or more of the MCSs are held in the communication terminal. The pre-calculated mappings are adjusted according to one or more transmission parameters of the data-carrying signals. Measures indicative of respective actual spectral efficiencies that are achievable by the MCSs are estimated based on the adjusted mappings using the received reference signals. A preferred MCS is selected based on the estimated measures, and feedback that is indicative of the preferred MCS is sent to the base station.

Abstract: A method includes holding in a receiver a definition of a codebook including precoding matrices, and a definition of multiple sub-codebooks including different respective subsets of the precoding matrices in the codebook. A sub-codebook is selected in coordination with a transmitter, for use in a given time interval or frequency range. A Multiple-Input Multiple-Output (MIMO) signal that is transmitted from the transmitter is received. Feedback is generated in the receiver based on the received MIMO signal. The feedback is indicative of one or more preferred precoding matrices, which are chosen from the selected sub-codebook and which are to be used in precoding subsequent MIMO signals in respective partitions of the given time interval or frequency range. The feedback is transmitted from the receiver to the transmitter.
