Comparison on PAPR and BER in resource allocation for MIMO-OFDMA based cognitive radio using diversity technique / Nur Ariffin Abdul Razak

Orthogonal Frequency Division Multiple Access (OFDMA) and Single Carrier Frequency Division Multiple Access (SC-FDMA) is suitable for high speed transmission in downlink transmission and uplink transmission respectively. Recently, spectrum sharing is widely used in the OFDMA-based system. Cognitive...
