摘要： Two or more data packets transmitted through a wireless channel are received using a receiver device. The two or more data packets are a result of two or more transmissions that are made sequentially in time at different center frequencies in order to span a desired bandwidth. Each data packet of the two or more data packets is transmitted at a single center frequency. Time differences and/or carrier phase differences among the two or more transmissions are estimated. A time-of-arrival of one or more data packets of the two or more data packets is calculated using each data packet of the two or more data packets and one or more of the estimated time differences, the different center frequencies, and the estimated carrier phase differences.

摘要： Techniques are provided to correct for phase and amplitude mismatches in a radio device in order to maintain channel symmetry when communicating with another device using a multiple-input multiple output radio communication. Correction for the amplitude and phase mismatches among the plurality of transmitters and plurality of receivers of a device may be made at baseband using digital logic in the receiver path, the transmitter path or both paths of that device. Amplitude and phase offsets are determined among the plurality of radio transmitter and radio receiver paths by measuring phase and amplitude responses when supplying a signal to a transmitter in a first antenna path of the device and coupling the radio signal from a first antenna to a second antenna path of that device where the signal is down-converted by a receiver associated with the second antenna path.

摘要： A system, method and device for MIMO radio communication of multiple signals between a first device (100) having N plurality of antennas (110) and a second device (200) having M plurality of antennas (210). At the first device, a vector s representing L signals to be transmitted is processed with a transmit matrix A to maximize capacity of the channel between the first device and the second device subject to a power constraint that the power emitted by each of the N antennas is less than or equal to a maximum power. The power constraint for each antenna may be the same for all antennas or specific or different for each antenna. For example, the power constraint for each antenna may be equal to a total maximum power emitted by all of the N antennas combined divided by N. The transmit matrix A distributes the L signals among the N plurality of antennas for simultaneous transmission to the second device. At the second device, the signals received by the M plurality of antennas are processed with receive weights and the resulting signals are combined to recover the L signals.

摘要： A system and method for determining the location of a device (target device) in a wireless radio environment. The method involves transmitting a first signal. The target device transmits a second signal. The first signal and second signal are received at two or more known locations in the general proximity of the target device. The location of the target device is computed from the time difference of arrival of the first signal and arrival of the second signal at the two or more known locations. This technique does not require the measurements made at the known locations to be time-synchronized, and can be performed completely in software, if desired, using non-real-time post-processing.

摘要： Methods are provided for identifying devices that are sources of wireless signals from received radio frequency (RF) energy (710). RF energy is received at a device called a sensor device herein. Pulse metric data is generated from the received RF energy. The pulse metric data represents characteristics associated with pulses of received RF energy. The pulses are partitioned into groups based on their pulse metric data such that a group comprises pulses having similarities for at least one item of pulse metric data (720). Sources of the wireless signals are identified based on the partitioning process (760). The partitioning process involves iteratively subdividing each group into subgroups until all resulting subgroups contain pulses determined to be from a single source (750). At each iteration, subdividing is performed based on different pulse metric data than at a prior iteration. Ultimately, output data is generated (e.g., a device name for display) that identifies a source of wireless signals for any subgroup that is determined to contain pulses from a single source (790).

摘要： An algorithm for correcting the output of an analog I/Q demodulator (10) without the need for calibration or storing state information. The output of the analog I/Q demodulator (10) is digitized, and the discrete-time samples are divided into segments. A digital frequency transform (e.g., a Discrete Fourier Transform) (35) is computed for each segment. The effects of the non-ideal 1/Q demodulator are removed by identifying a set of image frequency candidates for each digital frequency transform, and for each image frequency candidate, estimating a set of demodulator imbalance parameters to characterize the demodulator imbalance at that frequency and correcting the digital frequency transform at the image frequency candidate using the imbalance parameters in order to minimize the effects of the imbalance. Each digital frequency transform is corrected independently and consequently no persistent state information needs to be saved between transforms.
