摘要： The invention relates to an error correcting decoder apparatus (100) and method. The decoder apparatus (100) comprises a likelihood estimator (101) which generates a sequence of bit value likelihood estimates, such as log likelihood ratios, for multi bit symbols of a data sequence. The decoder apparatus (100) further comprises a decoder element (103), such as a Maximum A Priori (MAP) or appropriate Soft Output Viterbi decoder. The decoder element (103) generates a decoded data sequence in response to the bit value likelihood estimates. The decoder apparatus (100) also comprises a weighted processor (105) which generates a weighted compensation data sequence from the decoded data sequence. The weighted compensation data is used to modify the sequence of bit value likelihood estimates. The decoding is subsequently repeated using the improved bit value likelihood estimates whereby improved decoding performance is achieved. The invention may be applied to a two decoder element decoding apparatus (200) and may specifically be applied to turbo decoders.

摘要： A method, implemented by a router device, for guiding a user in establishing access privileges for a data exchanger includes causing the data exchanger to establish a remote link with a data service provider. Access content is obtained from the data service provider and presented to a client device. Access data provided in response to the presenting of the access content is received. The access content when presented by the client device enables a user to supply the access data. The access data is useable by the data service provider to set access privileges associated with the data exchanger that enable the data exchanger to be utilized to perform a desired function.

摘要： An apparatus, system, and method for isometric exercise that safely reduces resting blood pressure and increases overall cardiovascular health. The apparatus includes a handle or grip configured to provide natural resistance to force and maximize user comfort. The system includes squeezing the handle or grip of the apparatus with a force that is less than the maximum squeeze force of the user, thereby reducing blood flow through contracting arm muscles and safely increasing blood pressure during exercise. Resting blood pressure is reduced through regular use of the system. The method includes measuring and recording the maximum squeeze force of a user, calculating a fractional force using the duration of exercise or a desired fractional force percentage, and alternately inducing the user to apply the fractional force for a calculated time and inducing the user to apply a lesser fractional force or no force for a calculated time.

摘要： A system and method for controlling the gain in the forward signal path of a digital predistortion linearizer is disclosed. The loop gain of the predistortion system is driven to unity, where a separately controlled constant-gain observation path allows accurate gain control of the forward path. This is divided into digital gain from the predistortion function and analog gain from a Voltage Variable Attenuator (VVA) in the transmitter. The invention balances the distribution between these two domains in order to maximize dynamic range and minimize noise in the forward signal path. In order to distribute the forward path gain accurately, the characteristic of the VVA must be well known. Since these devices tend to be non-linear, with variable characteristic over temperature and batch, the invention compensates for this non-linear behavior by tracking the varying transfer characteristic of the VVA, giving a predictable local characteristic. Another aspect of the disclosed invention is the ability to operate with very low transmit power and loop gain levels, allowing accurate gain control during such scenarios as cell initialization, that require operation over a wide dynamic range.

摘要： A system and method for compensating for the time delay between the in-phase I and the quadrature Q paths of a digitally modulated transmitter incorporating an analog quadrature modulator is disclosed. The time delay between the in-phase I and the quadrature Q paths is computed and used to calibrate a set of interpolation filters in the forward path that compensate for this delay, reducing the frequency dependent degradation in performance of the analog quadrature modulator. The disclosed system and method provides improved compensation of gain, phase and DC offsets in the analog quadrature modulator over a broader bandwidth. Fractional delay interpolation filters may be used to estimate the delay between the in-phase and quadrature paths. This eliminates the need for a factory calibration procedure, speeding up manufacture and reducing costs.
