Title: Bo Engström: Innovator in CDMA Mobile Communication Systems
Introduction
Bo Engström is a notable inventor based in Luleå, Sweden. He has made significant contributions to the field of mobile communications, particularly in CDMA technology. With a total of 2 patents, his work has had a lasting impact on the industry.
Latest Patents
Engström's latest patents focus on power control in CDMA mobile communication systems. The first patent describes a method and apparatus for controlling transmission power levels in a CDMA cellular communication system. This innovation introduces a third control loop, which is interposed between an inner loop and an outer loop to create a cascaded power control loop. Quality indicators are coupled to both the outer and middle loops, allowing the outer loop to produce a quality target value for the middle loop, which in turn generates the SIR target value.
The second patent also addresses transmission power control in CDMA mobile communications. It provides a method and system that utilizes an estimate of the achieved SIR as an additional parameter for the outer power control loop function. In scenarios where both the QoS and achieved SIR are too low, the QoS is disregarded, and the SIR target value is controlled by the achieved SIR. Conversely, when both metrics are too high, the QoS is again ignored, allowing the SIR target value to be governed by the achieved SIR.
