Abstract: A receiver system (10) includes a first stage of modulation (46, 51) which modulates a radio-frequency input signal (17), and a second stage of modulation (56, 61, 66, 71) which modulates outputs from the first stage. Combining circuits (76, 77) combine selected outputs of the second stage to produce two outputs (18, 19) from the receiver system. The first stage receives modulating signals (22, 23) from a first oscillator (21), and the second stage receives modulating signals (27, 28, 32, 33) from second and third oscillators (26, 31). The second and third oscillators each operate at a substantially lower frequency than the first oscillator. The phase difference between the modulating signals produced by each of the second and third oscillators is adjusted so that there is minimum image power in each of the system outputs (18, 19), even if the modulating signals from the first oscillator are not in phase quadrature.

Abstract: A circuit is designed with a measurement circuit (746) coupled to receive an input signal from at least one of a first antenna and a second antenna of a transmitter. The measurement circuit produces an output signal corresponding to a magnitude of the input signal.

The control circuit is arranged to produce a control signal in response to a comparison of the output signal, the first reference signal and the second reference signal.

Abstract: The phase difference between a known stable reference signal (11) and a known signal output by a wireless mobile communication device (5, 5B) is determined at several known locations (1-4, 1B-4B). The location of the wireless mobile communication device is then determined from the phase difference information. Also, the approximate location of a wireless mobile communication device (5A) can be estimated by transmitting a message from the device at a predetermined power level (71), and determining where among a plurality of predetermined locations (1A-4A) the transmitted message has been received.

Abstract: A direct comparison adaptive halting turbo decoder computes the sum of the a priori and the extrinsic information sequences at each iteration step. The sum sequences are coded so as to be simple binary sequences. New sum sequences are generated during each iteration and used to estimate the state of the convergence without resorting to use of transmitted error detection codes. The adaptive halting turbo decoder is halted when the sum sequences generated in a single iteration step produce identical binary sequences, i.e. a change in the sum sequence is observed during the iteration and when there is no more change, the iteration is halted.

Abstract: A circuit simulator is provided for simulating the operation of a circuit in the time domain by accounting for the physical fluctuation (noise) in the time domain. Each of the components (14) in the matrix (10) has associated therewith an active current generator which can be simulated by the simulator in the time domain. In parallel with this active current generator, a stochastic (random) process current generator is provided. This stochastic current generator for each element will utilize a Gaussian random number generator (with 0 mean and a variance equal to 1) that is scaled by the standard deviation (square root of the variance) of the physical noise process that exists within the device. Additionally, this Gaussian random number generator is scaled by a factor that accounts for the time step or discrete operation of the noise simulator.
