SINR evaluation of OFDM-CDMA systems with constant timing offset: asymptotic analysis

Based on the proposed frequency do- main channel estimation scheme, a generic ~:quency domain equalizer (FDE}-based receiver architecture is eventually proposed.

In the last part, various detection techniques combined with the MC-CDMA modulation are proposed in order to limit the effects of the impulse noise.. On the one hand, sin-

• we prove that the CML algorithm yields an unbiased channel estimator, and that the second moment exists as long as the number of transmitted OFDM symbols is strictly greater

To improve the performance of the Multi Band OFDM (Orthogonal Frequency Division Multiplex) solution proposed by the Multi Band OFDM Alliance (MBOA), the addition of a

D’une manière générale, ces différentes contributions montrent que, par rapport à la solution MBOA « classique », outre une plus grande facilité dans le partage des

Abstract- This paper investigates the impact of carrier frequency offset (CFO) and sampling frequency offset (SFO) on the performance of different MIMO-OFDM schemes with

In the following, we cast our attention to initial synchronization and particularly to initial carrier frequency offset (CFO) estimation in orthogonal frequency division
