Title: Innovations of Darryn Lowe
Introduction
Darryn Lowe is an accomplished inventor based in Helensburgh, Australia. He has made significant contributions to the field of telecommunications, particularly in the area of orthogonal frequency division multiplexing (OFDM). With a total of 4 patents to his name, Lowe's work has advanced the efficiency and effectiveness of data transmission technologies.
Latest Patents
One of Lowe's latest patents focuses on orthogonal frequency division multiplexing using subsymbol processing. In this invention, a transmitter converts digital input data into combined-OFDM signals, while a receiver recovers data from these transmitted signals. The process involves mapping digital data into data symbols using modulation techniques such as QAM or DQPSK. The data symbols are divided into groups and converted into separate OFDM subsymbols using IFFT processing. These subsymbols are then combined to create a combined-OFDM symbol, which is prepared for transmission through various techniques, including spectral shaping and upsampling.
Another notable patent involves the demodulation of 16-QAM, DCM data symbols using two hybrid-QPSK constellations. This invention utilizes a demapper that employs two hybrid-QPSK constellations to demap pairs of equalized data symbols recovered from 16-QAM, DCM OFDM symbols. The process generates decision variables and calculates log-likelihood ratios to determine the likelihood estimates for the bits of the four-bit group.
