Title: Harmoko Habibi Roni and OFDM Signal Transmission

Introduction

Harmoko Habibi Roni is an inventor associated with Nantou County, ID (US), and with work connected to the Industrial Technology Research Institute and National Chi Nan University. His patent concerns signal transmission and reception in orthogonal frequency-division multiplexing (OFDM) systems.

Latest Patents

Roni is credited with 1 patent: “Signal Transmitting Method, Signal Receiving Method and Signal Receiving Device in OFDM System.” The invention uses double asymmetric training symbols to estimate time-varying channel responses. On the transmitting side, asymmetric pilot subcarriers are added among data subcarriers to create first and second training symbols with asymmetrically arranged pilots. On the receiving side, the channel response for each pilot subcarrier is estimated using two adjacent asymmetric pilot symbols, and that estimate is used to restore received data subcarriers. The approach is designed to support reliable data transfer even when a transmitter or receiver is moving at high speed, while allowing more bandwidth to be used for data.
