Abstract: An embodiment of a method and device for detecting a signal and generating bit soft-output of a multiple-input multiple-output system is provided.
The device includes at least one channel estimates pre-processing unit, one received vector processing and one detection and soft-output generation unit.
The pre-processing unit calculates multiple QR Decompositions of the input channel estimation matrix.
The detection and soft-output generation unit computes near optimal bit soft output information with a deterministic complexity and latency.
It may implement a reduced complexity search method.
Globally, embodiments of the invention may allow achieving low complexity, high data rate, scalability in terms of the dimension of the MIMO system and flexibility versus the supported modulation order, all potentially key factors for most MIMO wireless transmission applications.

Abstract: There is described a receiver (4) of a signal communication apparatus; the apparatus comprises a transmitter (1) adapted to transmit coded signals, the receiver (4) for receiving the signal and a wireless interface (3) interposed between the transmitter and the receiver and comprising a transmitting antenna (L1) and a receiving antenna (L2). The receiver comprises decoding means (12) of the received signal and first means (9, 10) coupled to the receiving antenna (L2) and capable of triggering said decoding means of the received signal if the value of the received signal is outside a logical hysteresis consisting of a first logic threshold (TH_LO) having a value smaller than the value of the direct current component of the received signal and a second logic threshold (TH_HI) having a value greater than the value of the direct current component (Irde) of the received signal.

Abstract: There is described a receiver (4) of a signal communication apparatus; the apparatus comprising a transmitter (1) for transmitting the signals, the receiver (4) for receiving the signals and a galvanically isolated wireless interface (3) interposed between the transmitter and the receiver and comprising a transmitting antenna (L1) and a receiving antenna (L2). The receiver comprises a disturbance rejection circuit (6, 52) coupled to the receiving antenna (L2) and capable of compensating for the parasite currents flowing between the transmitting antenna and the receiving antenna at the potential variations between the input and output of the galvanic isolation interface.

Abstract: A pump capacitor (Cpump) or alternatively an energy storing inductor (Coil) is charged by coupling it to a voltage source (VIN), thereafter the charged pump capacitor (Cpump) or energy storing inductor (Coil) is connected in parallel to one of said capacitors or capacitance cell to be charged. The sequence of different connections of the pump capacitor (Cpump) or inductor (Coil) to the charge voltage source (VIN) and to the selected one of the capacitors of the series is actuated through a plurality of coordinately controlled switches (A,B,C,D,E) that establish distinct current circulation paths, according to a switched-capacitor or switched inductor technique, all driven by respective periodic control signals, generated from a master clock signal. In charging all the capacitance cells substantially at the same time, at every charge/discharge cycle it may be decided which capacitance or cell is going to be charged by connecting in parallel thereto the charged pump capacitor (Cpump) or charged inductor (Coil), depending on the voltages detected on each capacitance cell of a super capacitor.
