In the field of visible light communication (VLC) systems, carrier-less amplitude and phase modulation have lately been explored as an alternative to various modulation techniques, especially optical orthogonal-frequency-division-multiplexing. This study simulates the performance of carrier-less amplitude phase (CAP) modulation compared to basic On-Off Keying in terms of bit-error-rate, constellation diagram and eye diagram. The performance of CAP-2, CAP -4 and CAP-8 was considered in this study due to low computational complexity. Based on various modulation orders of CAP signals, CAP-4 has the lowest EVM (-10.90 dB) and highest MER (11.30 dB) which indicates better performance, supported by good eyediagram representation. Non-square constellation diagram limits the performance of CAP-8 scheme.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
