Successive Interference Cancellation in Clipped and Product Combining aided FFH Multi-User Systems
— In this contribution, we propose two successive interference cancellation (SIC) schemes for a fast frequency hopping (FFH) multiple access (MA) system using M-ary frequency shi...

Differential Transmit Diversity Based on Quasi-Orthogonal Space-Time Block Code
By using joint modulation and customized constellation set, we show that Quasi-Orthogonal Space-Time Block Code (QO-STBC) can be used to form a new differential space-time modulati...
