Orthogonal frequency division multiplexing (OFDM) forms the basis of most present and future wideband wireless communication systems. The performance of such systems is largely governed by the inbuilt channel equalizer. The challenge in equalization for OFDM based systems is to estimate the channel coefficients with good accuracy. Also it is highly desirable to obtain these coefficients with minimum loss in the bandwidth efficiency. Thu, 01 Jan 2009 00:00:00 GMT http://127.0.0.1/xmlui/handle/123456789/645 2009-01-01T00:00:00Z
