variable-weight OCDMA - Opis:
- In this paper a Variable Weight OCDMA (VW-OCDMA) system using KS code with Direct Decoding (DD), Complementary Subtraction (CS) and AND subtraction detections is proposed. System performance is analyzed using mathematical approximation and software simulation. In mathematical analysis, the eects of Phase-Induced Intensity Noise, shot noise and thermal noise are taken into account. Bit Error Rate of dierent users is plotted as a function of received optical power per chip with varying the bit rates and number of active users. It has been shown that for dierent bit rates and number of users, system using DD has better performance than the system applying CS and AND detection. Using DD scheme, the number of active users are 100 while this value is 27 and 25 in case of using CS and AND detection, respectively, when the received optical power per chip is -10 dBm.
