| Main Objective: This project proposes to investigate the performance impairments of the orthogonal frequency division multiplexing ultra wideband (OFDM-UWB) radio signal transmission in fiber-to-the-home (FTTH) networks and optimize the system parameters through analytical and numerical simulation work, and to experimentally demonstrate the main results obtained. Particularly, the study and the assessment of the main system impairments is performed, such as: (i) electrical crosstalk associated with multi-channel OFDM-UWB transmission, (ii) linear and non-linear fibre effects, (iii) optical crosstalk associated with the transmission of several optical channels using dense wavelength division multiplexing (DWDM). Different techniques to reduce the performance degradation caused by such limitations are also investigated. The work to carry out along this project targets the transmission of OFDM-UWB radio signals in FTTH networks using external modulation (EM) and direct modulation (DM) of the emitter laser. The transmission of OFDM-UWB radio signals over multi-mode fibre is also a topic to be investigated in the project, since this type of fibre is used in the user’s premises due to its easy maintenance and utilization. |
