HIGH DATA RATE OF A NOVEL MODULATION SCHEME BASED ON ORTHOGONAL CHAOTIC SIGNALS
SINOPSIS
In a mobile environment and at high data rate transmission, channel makes highly hostility. This paper presents multi-orthogonal code modulation (MOCM) as a novel spread spectrum modulation scheme for spreading a transmission system to combat the channel effects and it is suitable for high data rate communications. This scheme uses an orthogonal chaotic signal to modulate and spread the information; therefore, a good information security is produced. The obtained results in noisy channel demonstrated the superiority of using MOCM compared with using traditional PSK for direct sequence spread spectrum (DS-SS); MOCM achieves a significant improvement in terms of bit error rate (BER) and data transmission rate.
