RZ-Gaussian pulses reduce the receiver complexity in wireless infrared links at high bit rates

Abstract

The performance of baseband infrared links, at 50 and 100 Mbit/s, in the same environment and for different signalling codes are compared. Results show that, on-off keying (OOK) format with return-to-zero Gaussian (RZ-Gaussian) pulses offer a simple alternative to other baseband schemes. The OOK modulation using RZ and RZ-Gaussian pulses simplifies the receiver structure regarding equalization and baseline restoration requirements in high bit rate links.
