Abstract: Embodiments provide a novel fabrication method and structure for reducing structural weight in radio frequency cavity filters (230, 330, 430) and radio subsystems such as antennas (502) and filters (230, 330, 430). The novel structures are fabricated by electroplating the required structure over a mold, housing, or substrate. The electrodeposited composite layer may be formed by several layers of metal or metal alloys with compensating thermal expansion coefficients. The first or the top layer is a high conductivity material or compound such as silver having a thickness of several times the skin-depth at the intended frequency of operation. The top layer provides the vital low loss performance and high Q-factor required for such filter structures while the subsequent compound layers provide the mechanical strength.

Abstract: A system and method for dynamically optimizing the transmission power levels for downlink voice and data signal transmitted from a base station (10) to user equipment (201 ) is disclosed. The user equipment (201 ) measures the strength and quality of the downlink signal, and transmits this downlink signal information to a control unit (96). The control unit (96) analyzes the downlink information and employs an adaptive self-learning traffic algorithm which determines optimized power levels for the downlink signals. The control unit (96) may optimize only one carrier signal or a subset of the multi-carrier signals in a preferred embodiment. The values of the optimized power levels are sent to the base station (10) which then increases or decreases the downlink transmission power of one or more carrier signals based on this level. As a result, the area associated with dead spots is reduced and the quality of the downlink signals is enhanced.

Abstract: A wireless repeater (10) includes an input antenna (12) for receiving an input signal, an output antenna (13) for outputting an amplified signal, and an amplifier (29) for amplifying the received input signal and providing the output amplified signal to the output antenna (13). Radiated coupling between the input and output antennas causes echoes to be transmitted by the repeater. A filter (210) is used for applying a weighting function to a power spectrum of a measured signal in the wireless repeater thereby obtaining a weighted power spectrum of the measured signal. An internal feedback path (150) is employed for adaptively canceling the echo by implementing an adaptive algorithm based on a autocorrelation of the input signal employing the weighted power spectrum of the measured signal.

Abstract: An improved radio frequency receiver and method enabling the dynamic range of a radio frequency receiver to be extended are disclosed. In the receiver system, the effective received channel power is a combination of the wanted signal level, the noise floor and any in band spurious signals generated from blocking signals present at the input to the receiver system. When this total effective channel power is known, the front end gain is optimized by adaptively minimizing the total effective channel power. Since the wanted input signal power does not vary with the receiver gain setting, this optimizes the noise figure and input intercept point for the presented input signal conditions.

Abstract: A pilot system and method is disclosed that increases the rate of convergence of the second loop alignment control in a feed forward amplifier. Both a pilot generation and detection system and search algorithm controlling the alignment are disclosed. By measuring the frequency of the generated pilot, phase information regarding the second loop cancellation transfer function can be inferred. Changes in the pilot frequency as the search algorithm makes steps in the second loop alignment indicate errors in the direction of the search. Using this pilot frequency measurement along with the existing log-power measurement of the residual pilot power improves the convergence speed because fewer steps will be made to reach the optimal alignment setting.
