Abstract: A method for performing joint detection includes adjusting a ranking order of codes in a matched filtering result, and a ranking order of column vectors in a system submatrix according to the power. The joint detection is performed using an adjusted matched filtering result and an adjusted system submatrix, and acquires demodulated signals corresponding to the codes. The codes that have high power will be demodulated first. This ensures accuracy of demodulation, inhibits erroneous propagation effect, and improves accuracy of the joint detection.

Abstract: Transaction exchanges are controlled between two integrated circuits in a system having the integrated circuits (ICs), a power supply supplying power to a link between the ICs, thereby enabling transaction exchanges between both ICs and a controller controlling the ICs and the power supply. This involves receiving an order at the controller, wherein the order requires the link to be closed. An instruction is sent from the controller to each of the two ICs, wherein the instruction causes each of the ICs to stop initiating new transaction requests. For each one of the ICs, in response to detecting that the one of the two ICs has stopped initiating new transactions, it is detected when all pending transactions initiated by the one of the two ICs have been executed. The link is closed in response to detecting that all pending transactions of both of the two ICs have been executed.

Abstract: A method of driving a mobile communication terminal in a cellular network, includes monitoring with a control unit of the mobile communications terminal, reception power levels between the mobile communication terminal and cellular network base stations at a predefined monitoring rate for each base station. Timing information values for a number of base stations are intermittently monitored by the control unit. Drift of the timing information values for at least two of the base stations is monitored and significant motion of the mobile communication terminal is deemed detected if at least one of the timing information values indicates a drift equal to or exceeding a given timing drift threshold. The predefined reception power level monitoring rate is reduced to a reduced reception power level monitoring rate for at least a number of the base stations as long as the motion of the mobile communication terminal is not significant.

Abstract: Systems and methods are described relating to a matcher that inputs partial vectors at a rate of 1 per clock cycle and delivers complete vectors at the output with an indication per vector of its validity. The matcher can copy a maximum number of valid elements from an input queue to target vector in-order each clock cycle and eliminate copied elements from the input queue. The completely filled target vectors are paired with the complete data vectors and outputted as composite vectors.

Abstract: An automatic gain control (AGC) method and system for a radio receiver are proposed in which the ACG comprises two AGC loops; a first loop controlling signal gain in the analog portion of the radio receiver, a second loop controlling gain in the digital domain after digitization of the received signal. The analog AGC loop has a slower response time than the digital AGC loop. When applied to a multi-branch diversity receiver, each branch has its own digital AGC loop, but the analog gain can be common to all branches, based on measurement of the analog signal in each branch.

Abstract: A process for decoding a signal being representative of a Space Time or Frequency Block coding during two signaling periods (STBC) or two parallel channels (SFBC) is provided. The process receives an OFDM signal received from at least one antenna. The process also performs an OFDM demodulation in order to generate N frequency domain representations of the received signal. Then the process performs a decoding process on said OFDM demodulated signal and groups the received signal in word code, Y=(y1, y2), to represent the signal that was received during two signaling periods (STBC) or two parallel channels (SFBC). The word code is then decoded into a matrix after which a lattice reduction algorithm is applied to the matrix in order to transform the matrix into a reduced matrix having a near orthogonal vector. Then it performs a detection process on the reduced matrix to improve noise and interference immunity.

Abstract: A clock signal for electronic circuitry is generated by generating, based on which one of a plurality of application use cases is presently active, a first signal that indicates a first selected one of a plurality of clock signal operating points. Based on the electronic circuitry's present speed requirement, a second signal is generated that indicates a second selected one of the clock signal operating points. For any given one of the application use cases, the speed requirement need not remain constant for the duration of the application use case. Based on whichever one of the first and second signals is associated with a higher clock frequency operating point, a third signal is generated that indicates which clock signal operating point (and possibly what voltage level) should be active. The third signal controls generation of a clock (and possibly also voltage level).
