摘要： A method is provided for transmitting data. A first device (121) generates a first signal (320) having a first duty cycle, comprising a first gated-on portion (323) and a first gated-off portion (326) a time slot (260); and a second device (125) generates a second signal (330) having second duty cycle, comprising a second gated-on portion (333) and a second gated-off portion (336) in the same time slot (260). The first gated-on portion (323) is generated during a first segment of the time slot (260) and the first gated-off portion (326) is generated during a second segment of the time slot (260), while the second gated-on portion (333) is generated during the second segment and the second gated-off portion (336) is generated during the first segment. Media access control (MAC) can be used to further define positions within time slots (250) and provide error correction, power control, and the like. A preamble (860) can be transmitted at an increased power level to facilitate acquisition.

摘要： A circuit (100) is provided for notching an incoming wireless signal. The circuit comprises: a notching mechanism (110) for receiving an incoming signal and generating a notched signal having reduced power at the notch frequency (320), the notch frequency being adjustable in response to a notching control signal; a signal parameter detector (165, 170, 175, 180, 185) for detecting a signal parameter of the notched signal (325); a controller (155) for receiving the signal parameter and for generating the notching control signal (315), the controller being configured to vary the signal parameter within a notching control signal range (340); and a memory (160) for storing the signal parameter and the notching control signal received from the controller in a notching database (330). The controller is configured to analyze the notching database to determine an optimal notching control signal to achieve a desired level of signal performance (345).

摘要： A method (600) for controlling a transmit power of an interface module (230) is provided. The method includes generating a transmit power code at a power code generator (240) (610); receiving the transmit power code at the interface module (620); receiving control signals at the interface module (650); and generating a transmit signal at a transmitter circuit (410) in the interface module based on the control signals and the transmit power code (660). In this method, the power level of the transmit signal is controlled by the transmit power code, and the transmitter circuit and the power code generator are formed on separate circuit elements.

摘要： A transceiver (400) is provided in an ultrawide bandwidth device, which includes an antenna (110), a transmitter circuit (145), and a receiver circuit (165). A transmitter amplifier (440) is provided between the antenna (110 ) and the transmitter circuit (145), and is configured to have an operational transmitter output impedance when the transceiver (400) is in a transmit mode and an isolation transmitter output impedance when the transceiver (400) is in a receive mode. A receiver amplifier (460) is provided. between the antenna (110) and the receiver circuit (165), and is configured to have an operational receiver input impedance when the transceiver (400) is in a receive mode and an isolation receiver input impedance when the transceiver (400) is in a transmit mode. The isolation transmitter output impedance is greater than the operational receiver input impedance, and the isolation receiver input impedance is greater than the operational transmitter output impedance. Thus, a transmitter and receiver can be isolated without using a transmit/receive switch.
