Symbol and Bit Error Rates Analysis of Hybrid PIM-CDMA
A hybrid pulse interval modulation code-division multiple-access (hPIM-CDMA) scheme employing the strict optical orthogonal code (SOCC) with unity and autoand cross-correlation constraints for indoor optical wireless communications is proposed. In this paper, we analyse the symbol error rate (SER) and bit error rate (BER) of hPIM-CDMA. In the analysis, we consider multiple access interference (...
متن کاملBit-error rate analysis for hybrid PIM-CDMA optical wireless communication systems
A hybrid pulse interval modulation – code division multiple access (PIM-CDMA) is proposed. Expression for bit error rate (BER) is given. Numerical results presented are compared with hybrid PPM-CDMA and OOK-CDMA schemes. For a low number of users PIM-CDMA achieves similar and marginally lower BER performance compared with PPM-CDMA and OOK-CDMA, respectively. For large number users it offers bet...
متن کاملBit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملAccurate Techniques to Evaluate Cdma Bit Error Rates in Multipath Channels with Imperfect Power Control
In this paper, a Simplified Expression for the Improved Gaussian Approximation (SEIGA) is presented for accurately evaluating Direct Sequence Code Division Multiple Access (DS-CDMA) bit error rates in multipath channels and systems with imperfect power control. Previous techniques for evaluating bit error rate performance of these systems can lead to overly optimistic results under a variety of...
متن کاملConsiderations on the bit error probability of optical CDMA systems
1 The most common metric for evaluating the performance of an optical communications system is the symbol error probability (SEP) versus the received optical power. In circuit-like optical systems employing binary transmission such as WDM, this SEP takes the form of the Bit Error Rate (BER) which is, in general, relatively constant. However, when considering an asynchronous multiple access Opti...
