Abstract: In an OFDM receiver, one of a plurality of antennas is selected based on a ratio X of two moving average integration values (first moving average integration value and second moving average integration value) that are calculated from a non-delay symbol and a delay symbol.

Abstract: In a digital broadcast receiver, when a bit error rate (BER) is larger than a threshold in a BER determining part, power is supplied to a first tuner and a second tuner for diversity reception.

This structure allows power supply to one of the tuners to be stopped in excellent reception environments, thus reducing power consumption.

Abstract: A MIMO wireless communication system and method reduces the number of recursive operations when decoding received data symbols by decoding the data symbols in pairs rather than on a per symbol basis. Decoding in pairs is facilitated by the determination that errors between selected pairs of data symbols are uncorrelated and identically distributed with a determined variance. Additionally, the system and method can order the pairs and provide decoding rules that result in an insignificant loss of performance for a wide range of signal-to-noise ratios (SNRs). Furthermore, the system and method exploit the structure of the error covariance matrix to reduce computational demands.

Error metrics calculated for each symbol are stored in memory. A soft symbol is generated based on said signal samples from the sampler, the channel coefficients and estimates of symbols computed.

Abstract: The present invention provides a method for carrier detection associated with the receipt of MIMO RF packet communications. This involves receiving multiple MIMO RF packet communications with multiple receiver pathways, wherein the RF packet communications each comprise a preamble and data. The RF packet communications are sampled by a carrier detector before, during or after conversion to baseband. The carrier detectors are used to produce a set of carrier detection metrics for each reception pathway. These carrier detection metrics may be combined arithmetically with those of other reception pathways to produce a multi-reception pathway carrier detect. Alternatively, these carrier detection metrics can be processed to produce a logical decision or binary detection signal value associated with each reception pathway, which is then logically combined with the logical decisions of other reception pathways to produce a multi-reception pathway carrier detect.

Abstract: The demodulator in the receiving module of the invention supplies a signal produced based on a signal level detected by a first detector to a second amplifier as an amplification degree adjustment signal. With this arrangement, when a second receiver works, an AGC voltage supplied to the second receiver is already close to an ultimately converging certain value. The AGC voltage supplied to the second receiver is thus stabilized in its value, from the value close to the ultimately converging certain value to the certain value. Accordingly, a time period required from the second receiver starts working until the AGC voltage supplied to second amplifier ultimately converges into the certain value is shortened.

Abstract: Transmit beamforming with receive combining uses the significant diversity provided by multiple-input multiple-output (MIMO) systems, and the use of orthogonal frequency division multiplexing (OFDM) enables low complexity implementation of this scheme over frequency selective MIMO channels. Optimal beamforming uses channel state information in the form of the beamforming vectors corresponding to all the OFDM subcarriers. In non-reciprocal channels, this information should be conveyed back to the transmitter. To reduce the amount of feedback information, transmit beamforming combines limited feedback and beamformer interpolation. In this architecture, the receiver sends back a fraction of information about the beamforming vectors to the transmitter, and the transmitter computes the beamforming vectors for all subcarriers through interpolation of the conveyed beamforming vectors.
