The book "Uplink Power Control for IMT Advanced" provides a comprehensive examination of the implementation of an uplink model for IMT-Advanced. It focuses on the analysis of the Bit Error Rate (BER) concerning various turbo coding approaches and subcarrier allocation schemes, including Localized Frequency Division Multiple Access (LFDMA), Interleaved FDMA (IFDMA), and Block Interleaved FDMA (BIFDMA). The study highlights the impact of nonlinear environments on the performance of these techniques and conducts simulations in both single-user and multi-user environments. Special attention is given to the analysis of the Near-Far effect and the introduction of nonlinearities through a threshold clipping model with varying clipping percentages. This detailed analysis provides valuable insights for professionals and researchers in the field of telecommunications.
