In this paper, analysis of the throughput and delay in a spectrally phase-encoded optical code-division multiple-access (OCDMA) system, using a simplified slotted packet network protocol is conducted. Steady-state throughput and average packet delay of the system are derived. In evaluating the performance of the system, only multiple access interference is(More)
In this paper we analyze the power performance of a spectrally phase-encoded optical code division multiple access (SPE-OCDMA) slotted packet network based on a simple protocol. The steady-state throughput and average packet delay are derived as a function of transmitted power. Gaussian approximation is used in our performance analysis to consider the shot(More)
Globalization of the semiconductor industry has raised serious concerns about trustworthy hardware. Particularly, an untrusted manufacturer can steal the information of a design (Reverse Engineering), and/or produce extra chips illegally (IC Piracy). Among many candidates that address these attacks, Design Withholding techniques work by replacing a part of(More)
We analyze the performance of a spectrally phase-encoded optical code division multiple access slotted packet network based on a simple protocol. The steady-state throughput and average packet delay are derived as two measures to assess the performance of the network. First, only multiple access interference is considered and other sources of noise are(More)
Channel distortion may dramatically degrade speech recognition performance in a distant environment. Authors in their recent work proposed a novel spectral subtraction method which they named it maximum likelihood based spectral subtraction (MLBSS). They indicated that recognition performance could be improved dramatically by adjusting filter parameters(More)
