Title: Maurizio Graziano: Innovator in Channel Estimation Technologies

Introduction

Maurizio Graziano is a prominent inventor based in Turin, Italy, known for his significant contributions to the field of digital communication. With a total of five patents to his name, Graziano has developed innovative systems that enhance the efficiency and accuracy of channel estimation in communication systems.

Latest Patents

One of Graziano's latest patents is focused on channel estimation using pilot symbols. This system is designed to estimate the transfer function of a transmission channel, such as the downlink channel in a CDMA system, where both pilot and data signals are transmitted. The system includes at least one estimator that produces first and second channel estimates from the pilot and data signals. A combination node is utilized to combine these estimates, resulting in final combined channel estimates. Additionally, the system features an interpolator module that interpolates the second channel estimates over a basic estimation reference time, ensuring equal numbers of channel estimates derived from both signals.

Another notable patent by Graziano is a memory-based device and method of channel estimation in a digital communication receiver. This invention involves a spread spectrum digital communication receiver that incorporates an input memory buffer for storing samples of an input signal. It also includes a code generator circuit for generating a re-generated user code. The device estimates a channel delay profile using a basic correlator that reads samples from the memory buffer and performs correlation operations to compute values of the channel delay profile energy.
