نویسندگان
چکیده
This article puts forward an examination of using OFDMA method like WiMax for future cellular systems. The main goal of investigation and simulation is Doppler Effect influence on orthogonality disturbance in critical but real situations. The simulation results, allow coming to conclusion that Doppler Effect influence on pilot signals leads to BER increasing. The paper proposes Doppler Effect limiting values for pilot signals using and another solutions for decreasing Doppler Effect influences on OFDMA systems. One of possible solutions can be FBS method.

Fuzzy Based Adaptive Weighted Multiuser Interference Cancellation in Ofdma Systems
Orthogonal Frequency-Division Multiple Access (OFDMA) is a multi-user version of the Orthogonal frequency-division multiplexing (OFDM). OFDMA is used in the mobility mode of IEEE 802.16 WirelessMAN Air Interface standard, commonly referred to as WiMAX. Multiple access is achieved in OFDMA by assigning subsets of subcarriers to individual users [1], [2]. The performance of these systems depend o...

This paper deals with the problem of resources allocation in the downlink of the radio mobile systems. The allocation of resources is established in the context of multi-path effect and Doppler effect. These phenomena cause randomly variations of the channel and make difficult the allocation of the resources. Therefore, the problem of resources allocation is a high non linear optimization probl...
متن کاملBICM-OFDM Systems over Time-Varying Channels: ICI Cancellation and Diversity Order Analysis
In high mobility scenarios, orthogonal frequency division multiplexing (OFDM) systems experience temporal channel variations within one symbol time to a degree resulting in that the orthogonality among subcarriers is destroyed by inter-carrier interference (ICI) and significant performance degradation may follow, if ICI is left untreated. This dissertation is concerned with the challenging prob...
متن کاملImproving the OFDMA performance with common carrier frequency offset correction
In an OFDMA system, different carrier frequency offsets (CFOs) are possibly raised due to the mismatch of local oscillators and the Doppler effect because of multiple-antenna channels. In spite of an initial CFO synchronization scheme able to be applied at transmitters, the compensation of residual CFOs is required at the receiver in order to eliminate the inter-carrier interference (ICI) for i...
