Orthogonal frequency division multiplexing (OFDM) is a multi-carrier technique that has recently received considerable attention for high speed wireless communication and ad hoc networks. In this paper we develop a simple pilot symbol assisted frequency domain beamforming technique for the OFDM receiver. The weight vector estimated with the proposed scheme(More)
A computer assisted learning software based on a bi-directional associative memory (BAM) network was developed. The software was implemented to assist students in associating the names of the elements in the periodic table with their chemical symbols. The use of the BAM facilitates the analysis and interpretation of students' responses. The software package(More)
