Title: Innovations by Pengpeng Song
Introduction
Pengpeng Song is a notable inventor based in Shanghai, China. He has made significant contributions to the field of data transmission technology. With a total of 3 patents to his name, his work focuses on enhancing system performance in communication networks.
Latest Patents
One of his latest patents is a "Data transmitting method with hybrid automatic repeat request in multi-carrier system." This invention provides a method where the signal-to-noise ratios of respective sub-carriers are compared with a threshold. The data on sub-carriers with lower signal-to-noise ratios are selectively retransmitted by mapping them onto sub-carriers with better channel conditions. This method effectively enhances system throughput without impairing the bit error rate.
Another significant patent is the "Hybrid automatic repeat request combining method in orthogonal frequency division multiplexing system." This invention adopts an improved Chase combining method weighted by SNR and variance of SNR to realize HARQ combining. It improves system performance in processing power and time delay, particularly in low SNR environments, without adding complexity to the system.
