The convergence of optical and wireless network has led to the trend of future access network . Under the study of Software Defined Radio Access Network(SD-RA) and Soft Frequency Reuse(SFR) system model, this paper presents a new inter-cell interference suppression algorithm of SD-RA network. The paper also summarizes and analyses the difference between the SFR based on coordinate multi-point transmission...
This paper presented a multi-rate Star-QAM encoding and decoding method based on the hierarchical coding which could be adjusted to achieve the channel coding efficiency and modulation. The design is based on the combination of soft / hard decision in layered decoding. We have successfully increased BER performance to 0.5dB which achieved 10−5 when SNR is 11 compared to no stratification codec considering...
A novel multi-amplitude minimum shift keying (MAMSK) orthogonal frequency division multiplexing (OFDM) signal is proposed for 60-GHz radio-over-fiber (RoF) access system. It can increase the tolerance toward frequency offset of an OFDM signal due to the faster roll-off side-lobe. In the experiment, a 3.21-Gb/s 2AMSK-OFDM signal is transmitted over 22 km single mode fiber (SMF) and 5 m air link successfully...
