Latest Patents

Lioumpas holds a patent titled "Method and apparatus for combining signals at wireless receivers in the absence of channel gain estimation." This invention addresses the challenges faced by diversity receivers that utilize multiple branches to receive signals transmitted through multi-path channels. The method minimizes combining loss in Equal Gain Combining (EGC) receivers, reduces Bit Error Rate (BER), and optimizes overall performance. The process involves estimating phase changes induced by the channel and weighting received signals to ensure they are co-phased. Additionally, it incorporates an optimization step that estimates the mean value and variance of the signal-to-noise ratio (SNR) in each branch, allowing for effective signal processing without the need for expensive hardware.
