O knihe

This book presents a study which involves an implementation of an IMT-Advanced Uplink model for the bit error rate (BER) performance analysis of Turbo coding, Different subcarrier mapping schemes e.g. Localized Frequency Division Multiple Access (LFDMA), Interleaved FDMA (IFDMA), Block Interleaved FDMA (BIFDMA) and Discrete Fourier Transform (DFT) precoding. ), Block Interleaved FDMA (BIFDMA) and Discrete Fourier Transform (DFT) precoding. These techniques have been implemented in linear and non-linear environments. Since pulse shaping has not been used so IFDMA performance analysis in non-linear environment was not possible with the non-linearity. Model used in this research. Hence the BER performance analysis in non-linear environments has been limited to BIFDMA and LFDMA schemes only. Non-linearities have been Introduced by using a threshold clipping model using three different clipping Percentages i.e. 1%, 10% and 30%. Moreover simulations have been performed for single user and multiuser environments, where we also analyzed the near far effect.
