Analysis of Indoor Wireless Infrared Optical CDMA LAN Using Prime Codes
In wireless optical system, CDMA suits well for high bit rate systems where good security is needed and mobility is not important. It would be economical when compared to radio frequency band and much safer since there is no electromagnetic effect. Infrared systems are used for its widest bandwidth and are not affected by radio transmission. The advantage of the prime code and the security issues in choosing the coding technique is noted. Prime codes would be much better than optical orthogonal code because of its heavier code weight. The error probability of prime codes and OOC is compared in infrared wireless OCDMA network. The bit error probabilities of Optical CDMA system using prime sequence codes are analyzed.
