System level design of baseband OFDM for wireless LAN

Open publisher page 1 citations

Abstract

Multicarrier or Orthogonal Frequency Division Multiplexing (OFDM) has gain recently an increased interest with the development of faster signal processing components and technologies. OFDM has been shown to be a very efficient scheme for mitigating the adverse effects of inter-symbol interference, squeezing multiple modulated carriers tightly together but keeping the modulated signals orthogonal so they do not interfere with each other's. This paper describes the system level model of the OFDM baseband and uses it to evaluate the BER performance.
