Introduction

Dingfei Ma is a prominent inventor based in Guangzhou, China. He has made significant contributions to the field of long-range communication technologies. With a total of 3 patents to his name, his work focuses on enhancing data transmission methods.

Latest Patents

One of his latest patents is a "Long-range radio communication method and device based on spreading factor index." This invention involves a method that divides information bits into index bits and modulated bits within one symbol period. It maps the index bits into a spreading factor sequence and generates first chirp signals corresponding to various spreading factors. The method ultimately aims to increase data rates by creating an additional dimension to carry more information bits.

Another notable patent is the "Coding method and device based on multiple-mode orthogonal frequency division multiplexing with index modulation (MM-OFDM-IM)." This coding method divides a coded bit sequence into an index-layer sequence and a symbol-layer sequence. It determines constellation modes corresponding to subcarriers and converts the coded bit sequence into constellation symbols, which are then loaded onto the subcarriers.
