A Performance Analysis of Optical Overlapping PPM-CDMA Communication Systems
Direct-detection optical code-division multiple-access (CDMA) systems employing overlapping pulse-position modulation (OPPM) schemes are proposed. Both upper and lower bounds on the bit error rate (BER) are derived taking into account the effect of both multiple-user interference and receiver shot noise. The photodiodes’ dark currents are neglected since their effect is minor. The throughput li...
متن کاملPerformance Analysis of Optical CDMA systems with PPM Signaling
An optical code-division multiple-access (OCDMA) system with M-ary pulse-position modulation (PPM) signaling is investigated. Latin-Square based optical orthogonal codes (OOCs) are proposed to be used in conjunction with modified prime codes as address sequences in our system. A union lower bound on the bit error rate (BER) is derived and the performance characteristics are then discussed with ...
متن کاملPerformance of OOK and Variants of PPM in APD based Free Space Optical Communication Systems
On-Off Keying (OOK) and Pulse Position Modulation (PPM) are the most commonly used modulation techniques in Free Space Optical (FSO) communications. In this paper, the performance of an FSO system with OOK and various PPM schemes has been analysed. The log-normal turbulence model for weak atmospheric turbulence and Avalanche Photo Diode (APD) receiver are considered for the system performance e...
متن کاملOptical Spread Time CDMA Communication Systems with PPM Signaling
We propose an optical spread-time codedivision multiple-access (ST-CDMA) with pulse position modulation (PPM) signaling for high-speed communication networks. We obtain a union upper bound on the bit error rate (BER) considering the multi-access interference (MAI), shot noise and thermal noise at the receiver. As a result, we show that the optical ST-CDMA with PPM signaling improves the BER per...
متن کاملDirect Detection Optical Overlapping PPM-CDMA Communication Systems with Double Optical Hardlimiters
Direct detection optical code-division multipleaccess (CDMA) communication systems involving overlapping pulse-position modulation (OPPM) is considered. Double optical hardlimiters placed before and after the correlator at the receiver side is proposed for this system. The performance (in terms of the bit error probability) of this system is evaluated taking into account the effect of both the ...
