Abstract: A method in a radio communication device having a receiver receiving a wideband signal in the presence of narrowband blockers method in direct conversion and intermediate frequency RF receivers including determining power for signal distortion products (40), determining power for a desired signal and the distortion products (41), filtering the signal distortion products with a filter having a bandwidth of rejection, and dynamically adjusting a rejection property (43) as a function of the power for both the desired signal and the signal distortion products. In some embodiments, a determination is made whether a ratio of powers exceeds a threshold (45) as a condition for adjusting the rejection property.

Abstract: The present invention provides a method and apparatus for generating time of arrival estimates for use by a wireless communication network for locating the position of a wireless or mobile source (102) within the service area of the wireless communication network. The mobile source generates time of arrival estimates from data bursts received from base sites (100) operating within the network. In at least one embodiment, the mobile source (102), then, communicates the time of arrival estimates for each of the base sites (100) to the network, from which the location of the mobile source (102) is determined. In at least some instances, the mobile units additionally determine a variance estimate for each time of arrival estimates, which is representative of the degree of confidence in the time of arrival information being supplied to the network.

Abstract: A dual mode wireless device in which a coefficient generator (42) generates parameter values for a GSM waveform, based on transmitted sequences of digital data values from a GSM unit (34), using a multiplierless operation, and a waveform generator (44) generating the GSM waveform using the generated parameter values. The coefficient generator includes adder sections (132, 136, 140), each having corresponding adders (142, 144, 146) and multipliers (148, 150, 152), register sections (154, 156, 158), each containing parameters corresponding to a modulator (48), and transmit data registers (TXDATA[5]-TXDATA[0]) sequentially receiving the digital data values from the GSM unit. The coefficient generator generates the parameter values for the GSM waveform by multiplying each of the parameters in the register section by a one or a negative one, responsive to the digital data values in the transmit data registers, and adding the resulting products to form corresponding coefficient generator output values.
