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

Abstract

The authors conclude that the on-off keying (OOK) format with return-to-zero Gaussian (RZ-Gaussian) pulses provides better performance than other signalling formats, more frequently proposed in reported works, allowing the adoption of a low-complexity receiver, and obviating the need for baseline restoration and equaliser filters. The above conclusion is validated by the corresponding bit error rate (BER) computation.
