Title: The Innovations of Stephen K How

Introduction

Stephen K How is a notable inventor based in San Diego, CA, with a remarkable portfolio of four patents. His work primarily focuses on advancements in digital signal processing and data encoding technologies.

Latest Patents

One of his latest patents is a device for equalizing channel-distorted signals. This equalization device features a digital equalizer designed for joint tuning of a data-carrying signal that has been distorted by analog transmission. The digital equalizer incorporates a closed-loop automatic gain control (AGC) circuit, which applies a compensatory frequency-independent gain to the distorted signal. Following this, a frequency filter is utilized to apply a compensatory frequency-dependent gain, resulting in an output signal that closely resembles the originally transmitted signal. This innovation facilitates the recovery of implicit clock signals and enhances data recovery reliability. Additionally, the digital equalizer can be implemented in stages, with a preliminary digital equalizer preceding an analog equalizer and followed by a final digital equalizer.

Another significant patent by Stephen K How is the punctured convolutional encoder. This invention provides a method and apparatus for convolutionally encoding digital data using a rate 4/5 convolutional code. A nonoptimal rate 1/2, sixteen-state convolutional code is punctured to achieve the rate 4/5 using a specific puncture map and octal generators. The incoming data stream is processed using this rate 4/5 code, and punctured rate 3/4 and 6/7 codes are also included in the invention.
