| Abstract: | Orthogonal frequency division multiplexing (OFDM) is an attractive technique. Because of its many excellent advantages such as higher frequency spectrum utilizing rate,lower cost and providing higher transmission rate,OFDM has been a part of the Radio LAN and MAN Standard. This paper discusses the advantages and key technologies of OFDM,compares OFDM with CDMA,and concludes that OFDM has superiority and application prosperity. |
| Keywords: | orthogonal frequency division multiplexing (OFDM) multiple access intersymbol interference(ISI) interchannel interference (ICI) |
