Abstract

In the present paper, a new coding scheme for infrared ASK communication systems-Pulse Sequence Modulation (PSM)-will be proposed, which uses a combination of pulse sequences so that it canattain zero-spectrum points at specific frequencies within the main-lobe region. The interference to the otherIR systems was a problem of the conventional infrared ASK communication systems. The proposed PSM coding scheme reduces the interference by decreasing the emission at specific frequencies, and helps multiple IR communicationsystems co-exist without deteriorating coding efficiency.
