Abstract: To increase the multiplexing capability of code-division multiplexing (CDM) applied in optical sensor networks, a system based code evaluation is required. This contribution analyses evaluation criteria for sequences applied in CDM systems. A comparison of an optical sensor application and a single user data transmission system is presented. While a detection signal-to-noise ratio and the bit error rate are used to evaluate data transmission systems, the proposed optical sensor application uses a modified signal-to-multiuser-interference ratio (mSMUI). The main difference exists in the handling of interference. In contrary to data transmission, the mSMUI requires a separation of positive and negative interferences. Both applications are simulated for different binary sequences. While the Legendre sequence with a length of 503 chips achieves the over all best results for the optical sensor application, the single user data transmission simulation shows no significant sequence influence.
