Albert L Garrett

Title: Albert L Garrett: Innovator in Wireless Communication Technologies

Introduction

Albert L Garrett is a notable inventor based in Melbourne, FL (US), recognized for his contributions to wireless communication technologies. With a total of 5 patents, Garrett has made significant advancements in the field, particularly in orthogonal frequency division multiplexing (OFDM) systems.

Latest Patents

Garrett's latest patents include a modified OFDM subcarrier profile, which introduces a 10 MHz channelized OFDM transmitter. This innovative transmitter communicates using a modified OFDM packet structure with a half-rate oscillator that maintains standard accuracy. The design features an inverse fast Fourier transform (IFFT) data processor that appends an outer pair of data subcarriers on either end of an OFDM subcarrier profile. Additionally, an IFFT long sync processor appends an outer pair of binary phase shift key (BPSK) subcarriers on either end of an OFDM long sync subcarrier profile. This approach allows for the copying or appending of information from data subcarriers closest to zero Hz to more robust locations, enabling 10 MHz channelized OFDM with half-rate clocks and 20 PPM oscillators.

Another significant patent is the power-based hardware diversity method for a wireless transceiver with multiple antennas. This method involves setting the transceiver gain at a maximum level to establish a dynamic power range above the noise floor level. It utilizes a high-resolution ADC at a large back-off level relative to the noise floor to detect weak signals within the dynamic power range. The process includes switching antennas and measuring power levels for each antenna during signal onset, ultimately selecting the antenna with the largest power level.
