Research ArticleOpen accessEvery word in the titleTurbo-coding of Coherence Multiplexed Optical PPM CDMA System With Balanced DetectionK. Chitra, V.C. RavichandranThe effects of turbo-coding on the coherence multiplexed optical PPM CDMA systems are shown by evaluating bit error rate (BER) with respect to system parameters such as interleaver length (K), number of simultaneous users (N), code length (f), initial pulsewidth (t0) and normalized threshold (θ) by including the effects of thermal noise and shot noise. Turbo-codes increase the number of … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,617 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Single Core Hardware Module of a Data Compression Scheme Using Prediction by Partial Matching TechniqueJubayer Jalil, Md. Mamun, Mohd. Marufuzzaman, Hafizah HusainProblem statement: Compression is useful because it helps reduce the consumption of expensive resources, such as hard disk space or transmission bandwidth. For effective data compression, the compression algorithm must be able to predict future data accurately in order to build a good probabilistic model for compression.
