The transmission performance in terms of root-mean-square error, error-vector magnitude, bit-error-rate (BER), and the overhead of redundant PTs was improved by using the proposed technique in 20-km CO-OFDMA-PON uplink transmission. Both MNs were effectively compensated by comparing transmitt...
Cochannel interference has been the bottleneck to the capacity of cellular network. To solve this issue, a virtual multiple-input multiple-output (MIMO) system can be constructed for the uplink OFDMA cellular system. However, if multiple cochannel MIMO clusters are used, they will still interfere...
Optical polarizationThe state of polarization (SOP) is a critical issue faced by the single-wavelength-based orthogonal frequency division multiple-access passive optical networks, because each optical network unit uses different polarization-sensitive optical devices and paths. To compensate SOP variation,...
This paper proposes a co-channel interference (CCI) reduction scheme for cell edge users in OFDM systems using same frequency. The proposed scheme includes a joint channel-estimation method with interpolated sliding window (JCE-ISW) and a joint detection with QRM-MLD based on the maximum ...
Ofdma-based co-channel femtocell.A femtocell increases efficiency and coverage of a macrocellular network operating in a co-channel manner within the macrocell spectrum by selecting subcarriers for its mobile station using both the subcarrier allocation map received from the macrocell and a spectrum ...
A femtocell increases efficiency and coverage of a macrocellular network operating in a co-channel manner within the macrocell spectrum by selecting subcarriers for its mobile station using both the subcarrier allocation map received from the macrocell and a spectrum sensing operation. Interference is ...
