This paper presents a novel diversity and absolute combining time domain transmitter (DACTDT) for the Enhanced Asymmetrically and Symmetrically Clipped Optical (EASCO) OFDM system. This system estimates and eliminates the clipping distortion of the signal at the transmitter. The spectral efficiency and bit-error-rate (BER) were improved. The DACTDT effectively combines time domain diversity combining technique (TDDT)-applied to ACO-OFDM stream and the novel absolute combining time domain technique (ACTDT)-applied to ESCO-OFDM stream. Both TDDT and the proposed ACTDT utilize the clipping distortion of their respective streams to improve their performance. In terms of Optical Signal-to-Noise Ratio (OSNR), at a BER of 10-3 with 1024-QAM, the proposed EASCO-DACTDT OFDM performs 8.3 dB better than EASCO-OFDM.

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.
