Threshold Determination of SC-FDMA System using Resource Allocation
Communication signals over power-line channels can be affected greatly by impulsive noise (IN). The effect of this noise is commonly reduced with the application of a nonlinear preprocessor at the receiver such as blanking or clipping that blanks and/or clips the received signal when it exceeds a certain threshold. Erroneous blanking/clipping of the unaffected signals can lead to significant pe...
متن کاملBER Performance using Almouti-Based SC-FDMA using PN Codes
Due to various shortcomings of OFDM, like it is sensitive to Doppler shift, frequency synchronization problems, loss of efficiency caused by cyclic guard interval, it was endorsed to use coding algorithms like STBC which improves efficiency. Another way of increasing the efficiency is using a multiple – access technique like SC-FDMA. SC-FDMA can be described as linearly Pre-Coded OFDMA scheme, ...
متن کاملA Low PAPR Visible Light Communication System Employing SC-FDMA Technique
White light emitting diode (WLED) technology has been regarded as an environment-friendly lighting in the future. The WLED lighting system is able to provide short range wireless communication while illuminating rooms. The WLED based visible light communication (VLC) systems employing orthogonal frequency division multiplexing access (OFDMA) technique has been investigated in many researches. H...
متن کاملFPGA Implementation of Wavelet based SC - FDMA System
Orthogonal Frequency Division Multiple Access (OFDMA) has recently been applied widely in wireless communication systems due to its high data rate transmission capability with high bandwidth efficiency and its robustness to multi-path fading. But it has several inherent disadvantages such as the large PAPR and the sensitivity to Carrier Frequency Offset (CFO).Hence much attention has been focus...
متن کاملLow Complexity CFO Compensation Scheme for SC-FDMA Uplink System
Single Carrier Frequency Division Multiple Access (SC-FDMA) has been adopted for fourth generation (4G) mobile uplink transmission schemes because of its low Peak to Average Power Ratio (PAPR) as compared to that of Orthogonal Frequency-Division Multiple Access (OFDMA).Since SC-FDMA has low PAPR, it is sensitive to Carrier Frequency Offsets (CFOs) similar to that of OFDMA. To minimize and compe...
