An ant colony genetic fusion routing algorithm based on soft define network
IET Networks, EarlyView., 2022 Abstract Aiming at the problem that there are many paths in data forwarding in soft define network (SDN) network, and the optimal path is difficult to find, combined with the advantages of ant colony algorithm and Genetic algorithm (GA), a routing control strategy based on the ant colony genetic fusion algorithm is proposed.

Frequency estimation in multipath rayleigh-sparse-fading channels [PDF]
, 2004 Maximum-likelihood (ML) data-aided frequency estimation in multipath Rayleigh-fading channels with sparse impulse responses is investigated. We solve this problem under the assumption that the autocorrelation matrix of the pilot signal can be ...

Modeling the air-ground multipath channel [PDF]
2017 11th European Conference on Antennas and Propagation (EUCAP), 2017 The paper proposes a geometrical-statistical modeling approach for the air-ground channel for communications, navigation, and surveillance (CNS) systems in the L-band frequency range. We sketch the architecture of the model with its six elements and show how their parameters can be derived from measurement data.

Robust OFDM Timing Synchronisation in Multipath Channels
EURASIP Journal on Wireless Communications and Networking, 2008 This paper addresses pre-FFT synchronisation for orthogonal frequency division multiplex (OFDM) under varying multipath conditions. To ensure the most efficient data transmission possible, there should be no constraints on how much of the cyclic prefix ...

Weighted target detector via estimated SNR in a multipath environment
The Journal of Engineering, 2019 Multipath effect cause serious performance degradation in low-altitude target detection. To overcome the negative multipath effect in a low-altitude environment, a novel weighted detector based on the estimated signal-to-noise ratio (ESNR) is proposed ...

Performance degradation due to multipath noise for narrowband OFDM systems: channel-based analysis and experimental determination [PDF]
, 2015 The performance of OFDM systems over a multipath channel can strongly degrade due to the propagation delay spread. The distortion of the received signal over the fast Fourier transform window is referred to as multipath noise.
