Narrowband Interference Suppression in Wireless OFDM Systems
Signal distortions in communication systems occur between the transmitter and the receiver; these distortions normally cause bit errors at the receiver. In addition interference by other signals may add to the deterioration in performance of the communication link. In order to achieve reliable communication, the effects of the communication channel distortion and interfering signals must be red...
متن کاملInter-Cell Interference Coordination (ICIC) Technology
Long Term Evolution (LTE) is a promising standard for next-generation cellular systems targeted to have a peak downlink bit rate of 150 Mb/s. However, as adjacent cells use the same frequency, interference between adjacent cells may degrade the bit rate at cell edges, preventing sufficient throughput from being obtained. Inter-cell interference coordination (ICIC) is a promising technology for ...
متن کاملAn Efficient Inter Carrier Interference Cancellation Schemes for OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) has recently been used widely in wireless communication systems. OFDM is very effective in combating inter-symbol interference and can achieve high data rate in frequency selective channel. For OFDM communication systems, the frequency offsets in mobile radio channels distort the orthogonality between subcarriers resulting in Inter Carrier Inter...
متن کاملIntercarrier Interference Suppression for OFDM Systems Using Hopfield Neural Network
In Orthogonal frequency division multiplexing (OFDM) transmission system, channel variations within an OFDM symbol destroy orthogonality between subcarriers, resulting in intercarrier interference (ICI), which increases an error floor in proportional to normalized Doppler frequency. To mitigate the effects of channel variations, in this paper, we propose a novel ICI suppression technique, which...
متن کاملNarrowband Interference Suppression for MIMO MB-OFDM UWB Communication Systems
Ultrawideband (UWB) systems show excellent potential benefits when used in the design of high-speed digital wireless home networks. The constantly-increasing demand for higher data transmission rates can be satisfied by exploiting both multipathand spatial-diversity, using multiple-input multiple-output (MIMO) together with proper modulation and coding techniques. Unlike conventional MIMO OFDM ...
