Deskripsi
Utilizing symmetric compression in time-frequency space, we can eliminate the crosstalk between real and imaginary components, and thus simplify the decoding complexity significantly in a non-orthogonal discrete multi-tone transmission system. The experiments are also demonstrated for an intensity-modulated direct detection system with the decoding complexity decreased to 1/4 for 13.8 Gbit/s QPSK and 1/8 for 27.6 Gbit/s 16-QAM with 1310 nm transmission over 40 km SMF.
