20130235905 | GATEWAY WIRELESS COMMUNICATION INSTRUMENT, WIRELESS COMMUNICATION SYSTEM, AND COMMUNICATION CONTROL METHOD - A period is defined to execute the sequences (processes) of communication data acquisition, measuring communication quality, communication quality data acquisition, and channel change.

For communication stations sharing timeslots, there are provided offset periods differing in length before the start of carrier sense in the timeslots for these stations. Consequently, even under a condition in which packet collision may occur, the collision of packets can be avoided by detecting a packet sent to another station by carrier sense.

At the same time, the low input impedance of the common-base/gate PA reduces the voltage swing at the transmitter output and prevents the transmitter output from being compressed or modulated, In an embodiment, the DC output current of the transmitter is reused to bias the PA, which results in power savings compared to conventional transmitter topologies. | 2013-09-12 |
20130235954 | Transmitter Gain Control and Calibration - Embodiments provide improved systems and methods of gain control and calibration for wireless transmitters. In particular, embodiments allow linear gain control over the entire transmitter gain control range, independent of temperature/process variations. Embodiments require very low power consumption compared to existing approaches. Embodiments may also be used for gain control calibration during production time, thereby substantially reducing production calibration time and cost. | 2013-09-12 |
20130235955 | SYSTEMS AND METHODS FOR PEAK DETECTION IN AUTOMATIC GAIN CONTROL CIRCUITS IN HIGH-SPEED WIRELINE COMMUNICATIONS - Methods and systems for peak detection as part of automatic gain control in high-speed communications are provided. A peak detection system uses a portion of an input signal to generate a reference signal for comparison with the input signal. The comparison produces a differential error signal that is in turn used to produce one or more full swing pulses based on the comparison. A pulse counter counts the pulses, and if the count in a single clock cycle is above a determined threshold, a binary error signal is set to indicate a need for correction. | 2013-09-12 |
20130235956 | STABILITY CONTROL IN SIGNAL DETECTION THROUGH CODE AND TIME DOMAIN CONDITIONING - In wireless communication systems, received signal estimation and detection is computationally intensive. During such processing, received signal matrices may be conditioned prior to inversion to improve stability. In particular, code domain conditioning, followed by time domain conditioning prior to inversion results in improved receiver performance. Such code and time domain conditioning may be particularly suited to a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system where code values are not averaged out of a received signal matrix. | 2013-09-12 |
