Title: The Innovations of Pedro M Crespo
Introduction
Pedro M Crespo is a notable inventor based in Madrid, Spain. He has made significant contributions to the field of telecommunications, holding a total of seven patents. His work focuses on advanced digital signal processing techniques that enhance communication systems.
Latest Patents
Among his latest patents is a wideband digital equalizer designed for subscriber loops. This invention utilizes a digital decision feedback equalizer that incorporates both finite impulse response (FIR) and infinite impulse response (IIR) filters in parallel within the feedback path. The FIR filter addresses the rapidly changing region of the channel impulse response, while the IIR filter compensates for the gradually decaying tail of the impulse response. Additionally, modifications of a sequential identification algorithm are employed to adapt the filter sections effectively. Another significant patent involves a spread-time code division multiple access (ST-CDMA) technique, which allows for bandlimited access to a channel. This technique assigns pseudo-random sequences to each transmitter in a multi-transmitter system, enhancing the efficiency of data transmission.
