Latest Patents

One of his latest patents is titled "Receive Decorrelator for a Wireless Communications System." This invention focuses on the decorrelation of signals to enhance coding gains in wireless communications. The design includes a branch signal processor that utilizes a summer to calculate the sum of two branch signals, producing a sum signal. Additionally, a conjugate swapper is employed to create swapped signals from the branch signals, transforming their real and imaginary parts. A differencer then determines the difference between the swapped signals, which is combined with the sum signal by a diversity combiner.

Another significant patent is the "Space Time Labelling Technique for Wireless Communication Systems." This technique involves a transmitter that incorporates two distinct bit mappers and transmitters. A processor manages the flow of two bit streams, mapping them into various bit streams for transmission in different time slots. This innovative approach allows for efficient use of time slots and enhances the overall performance of wireless communication systems.
