Patent CA-2175749-A1 (CA)
Inventor: WANG HE F
IPC: H04B1/04
Filed: 1996-05-03
Abstract: An output power control system prevents saturation by limiting total output power and maintaining closed loop responsiveness for a radio telephone having closed loop and open loop gain control systems. The output power control system determines when total output power exceeds an output power trigger level and automatically enters a saturation prevention mode whereby total output poweris reduced through modification of a closed loop power control register. In one embodiment, an output detector and an output comparator continuously monitor output power, and in another embodiment, an analog-to-digital converter samples output power levels. Saturation prevention processes of various preferred embodiments include, through continual monitoring, edge-triggered interrupt servicing, and level-triggered interrupt servicing, subsequently modifying the closed loop power control register to decrease the closed loop output power control portion of the total output power until the output power falls below theoutput trigger level. A saturation prevention method of yet another embodiment includes maintaining the closed loop power control register at a constant level unless a decrease in received signal strength is detected, in which case the closed loop power control register is modified to compensate for an increased open loopcomponent of the total output power.
Patent CA-2178847-A1 (CA)
Inventor: MARSHALL STEPHEN W
IPC: G05B11/42
Filed: 1996-06-12
Abstract: A tracking filter (10,80) which transitions from a type 2 loop to a type 1 loop as the loop error approaches 0 for fast settling and convergence without overshoot or ringing. The filter can either be implemented as an analog circuit (10) in hardware or digitally (80) is software. A first integrator (30) or first accumulator (82) is utilized to increment or decrement a discriminator (22,96) output error value as long as the sign of its output (32) from the previous iteration is the same as a sign of the error signal provided to its input (26) by the error discriminator (22,96). The first integrator output is limited to a range by a limiter (42) between a minimum and maximum value. If the sign of the first integrator output is different from the sign of the input, the contents of the first integrator or accumulator are dumped. The output from the first integrator or first accumulator has binary scaling (44,94) to scale its value before adding it to a second integrator (50) or second accumulator (88).
