| Popis: | In this paper, we demonstrate a spectrally efficient twin-SSB single carrier system based on multiple-input multiple-output (MIMO) processing. MIMO processing based on training sequence aided and decision-directed least mean square (LMS) is applied to mitigate the crosstalk introduced by non-ideal optical filters in receiver. The number of taps used in MIMO is evaluated. In addition, performance of Kramers–Kronig receiver and one-stage signal–signal beat interference (SSBI) mitigation algorithm is compared. 264 Gb/s per polarization in C-band transmission over 80 km SSMF with a net bit rate of 220 Gb/s using 88 GSa/s DACs is experimentally demonstrated with KK receiver. |
