In this paper, we investigate the connectivity of vehicular ad hoc networks in free-flow traffic situation with channel randomness. In order to illustrate the r
Clustering provides an effective way to prolong the lifetime of wireless sensor networks.One of the major issues of a clustering protocol is selecting an optima
By using d-form function,a new construction of frequency hopping sequence with optimal Hamming correlation is presented in this article,which generalizes the re
The problem of improving the performance of min-sum decoding of low-density parity-check(LDPC)codes is considered in this paper.Based on rain-sum algorithm,a no
Monolithic integration of resonant tunneling diodes(RTDs)and high electron mobility transistors (HEMTs)is an important development direction of ultra-high speed
