By processingso, the effect of ICI on the OFDM system is reduced aspossible, and its bandwidth efficiency has rare loss.In this paper, a new ICI cancellation scheme and itsarchitecture are presented in Section II. The symbol shiftcancellation (SSC) method and the adjacent sub-channelinterference filter (SSC-ASIF) scheme is respectively discussedin Section III and IV, and then BER performance of the OFDMsystem with the ICI cancellation scheme proposed in this paperis simulated and analyzed in Section V.

er system where data bits are encoded to multiple sub-carriers and sent simultaneously in time. The result is an optimum usage of bandwidth. A set of orthogonal sub-carriers together forms an OFDM symbol. To avoid ISI due to multi-path, successive OFDM symbols are separated by guard band. This makes the OFDM system resistant to multi-path effects. Although OFDM in theory has been in existence for a long time, recent developments in DSP and VLSI technologies have made it a feasible option. This paper describes the VLSI implementation of OFDM in details. Specifically the 802.11a OFDM system has..................[:=> Show Contents <=:]

INTRODUCTION

In this paper we consider a multiple-input multiple-output (MIMO) system in conjunction with orthogonal frequency division multiplexing (OFDM) operating over frequency selective Rayleigh and Rician fading environments. In particular we focus on the eigenvalues of the complex Wishart matrices defined for each OFDM subcarrier and investigate their variation across frequency. Since the throughput and performance o..................[:=> Show Contents <=:]

If the average power of the shortened symbols is kept the same, the variance of the estimate of einitial will be larger than for the longer data symbols,since it estimates the fraction of carrier spacing, corresponds to a proportionately larger fractional off..................[:=> Show Contents <=:]

WDM , multiple signals are carried together as separate wavelengths of light in a multiplexed signal. WDM is used in optical Fiber networks. It uses the same principle of FDM but applying to wavelength of light in optical fiber. WDM resembles FDM in that idea is to send information signals that occupy the same band of frequencies through the same fiber at the same time without interfering with each other. This is accomplished by modulating injection laser diodes that are transmitting highly concentrated light waves at different wavelengths. Therefore WDM is coupling light at two or more discre..................[:=> Show Contents <=:]

The signal whitener reduces the peak to average power level ratio that
must pass through the radio amplifiers and A/D converters; it can also
provide a level of security. The W-OFDM symbol is multiplied by a
vector of complex value, R that is known to the transmitter and
receiver. There are many vectors that can be used for, R and different
