Interference Mitigation Strategies for WiMAX Networks
2007 4th International Symposium on Wireless Communication Systems, 2007WiMAX IEEE802.16e systems are intended to provide high spectral efficiency in order to support services with challenging QoS constraints in heterogeneous scenarios. However, when addressing such goal, it is important to consider in detail the impact of deployment related issues.

MUOS U2B Interference Mitigation Analysis
MILCOM 2007 - IEEE Military Communications Conference, 2007This paper analyzes the effects on signal-to-noise ratio (SNR) caused by undesired interference within the user-to-base (U2B) MUOS spectrum, and the spectral modifications of the WCDMA waveform designed to combat such interference. Spectral modifications consist of waveform whitening and notching, and are applied to improve performance in the presence ...

HF Radio-Frequency Interference Mitigation
IEEE Geoscience and Remote Sensing Letters, 2010The dense radio-frequency interference (RFI) distributed on the spectrum in the high-frequency band greatly degrades the performance of radio systems and makes it urgent to find an effective and speedy method to eliminate the interferences. The interference mitigation method introduced in this letter is implemented before any further signal processing.

Electro-optic cosite interference mitigation
SPIE Proceedings, 2010Cosite interference can be roughly defined as the unintentional degradation of receiver functionality as a result of close proximity to a powerful in-band transmission source; for instance receivers located on modern cellular communication towers often suffer as a result of co-site interference introduced through space limitations and overcrowding ...

Project Sanguine Interference Mitigation Research
IEEE Transactions on Communications, 1974The Navy's proposed extremely low frequency (ELF) communications system (Sanguine), which would use an earthreturn circuit to excite the earth-ionosphere cavity, represents a potential electrical interference problem. The electromagnetic fields produced by Sanguine could influence other systems such as power distribution lines and telephone circuits ...

Interference Mitigation for Satellite
2017For the coexistence and increasing interference of satellite-terrestrial network and terrestrial wireless network, we analyze a typical scenario where the GEO satellite-terrestrial network and the 4G mobile communication network coexist heterogeneously.

Interference Mitigation in Cognitive Femtocells
2010 IEEE Globecom Workshops, 2010Femtocells are expected to take a major role on increasing the data rates on cellular network access over the next years. However, femtocells pose significant challenges, especially in terms of interference management and mitigation. In femtocell scenario, the costs for tradional network planning, management and optimization can be prohibitive. Instead,

Mitigating interference into communication satellites
2001 IEEE Aerospace Conference Proceedings (Cat. No.01TH8542), 2002This contribution outlines INTELSAT's efforts to reduce interference in the INTELSAT space segment by implementing an Interference Management Program (IMP) in conjunction with a Transmitter Locater System (TLS) tool to identify the geo-location of an interfering transmitter.

Interference Mitigation Based on Enhanced Interference PMI Notification
2012This paper considers interference mitigation in multicell scenarios where transmitters and receivers are both equipped with multiple antennas. In multicell system, both the local Pre-coding Matrix Index (PMI) and the interference PMI can be utilized by Interference Reject Combing (IRC) algorithm, and more interference information can be obtained from ...
