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 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 ...
متن کاملJoint Narrowband Interference Detection and Channel Estimation for Wideband OFDM
Narrowband interference reduces performance of present transmission systems, and will do so in the future to an even higher extent. The interference mainly hinders a correct data signal detection. But it may already have distorted the channel estimation, even for more carriers than the one, actually containing the carrier of the narrowband interferer. Therefore it is substantial to correctly de...
متن کاملNarrowband Interference Suppress in Spread Spectrum through Snr Improvement
Spread Spectrum (SS) communications offers a promising solution to an overcrowded frequency spectrum aimed growing demand for mobile and personal communication services. The proposed overlay of spread spectrum signal on existing narrowband users implies strong interference for the SS system. This paper discusses how the system performance can be improved by preprocessing to suppress narrowband ...
متن کاملOFDM Narrowband Interference Estimation Using Cyclic Prefix Based Algorithm
OFDM systems experience BER degradation in the presence of narrowband interference (NBI). We propose a novel NBI cancellation algorithm for a wideband OFDM receiver. Modelling the NBI as a single-tone sinusoid, subspace-based (SB) methods can be used to estimate it. However, direct application of SB methods to the received signal yields poor results except when the system is operating at very l...
