This paper presents, a two stage krill herd algorithm (TKHA) to address optimum power flow (OPF) issue in complex power system. Proposed algorithm implemented with two stage initialization approach provide optimal solution of the objective functions individually with less number of iterations which minimize the overall convergence time. The validity of TKHA(More)
The IEEE802.11a standard uses Orthogonal Frequency Division Multiplexing (OFDM). It can provide data rate up to 54 Mbps in Wireless Local Area Networks (WLAN's). This standard is used in indoor applications as well as in vehicles i.e. mobile environments. In this paper, we evaluate Bit Error Rate (BER) by changing the number of pilots using multiple(More)
