Differential APSK & QAM in Uplink Massive MIMO Systems
碩士 === 國立中央大學 === 通訊工程學系 === 107 === Massive MIMO systems are popular studies in recent years. Differential encoding scheme is not required to transmit pilot sequence for channel estimation, so it does not cause pilot contamination. A differentially encoded QAM (quadrature amplitude modulation) sche...
