Title: Johan Backman: Innovator in Radio Communications
Introduction
Johan Backman is a notable inventor based in Stockholm, Sweden. He has made significant contributions to the field of radio communications, holding 2 patents that enhance the efficiency and reliability of communication systems.
Latest Patents
One of Johan's latest patents is a bit detection method in a radio communications system. This invention focuses on the detection of bits that are protected by repetition, utilizing associated soft values to measure the reliability of received values. It is particularly applicable in speech encoding within the GSM mobile communications system, specifically for detecting class 2 bits known as pulse bits. These pulse bits are duplicated, resulting in a total of twelve bits, and the associated soft values improve the detection process beyond traditional methods that rely solely on majority decision-making.
Another significant patent is for selective diversity combining, which is a method and system for combining signals in a receiver that employs antenna diversity. This technique allows for the selection of diversity combining methods based on interference levels, utilizing interference rejection combining (IRC) when interference exceeds a predetermined threshold, and maximum ratio combining (MRC) when it does not.
