Figure 3From: Space-time code diversity by phase rotation in multi-carrier multi-user systemsCode diversity for multi-carrier and multi-user system. Comparison among exhaustive search (ES) - blue circles, the proposed algorithm (PA) with ZF decoding - red diamonds, and proposed algorithm with ML decoding - green stars. N=256. Nu=2,4,8,16,32. Code diversity achieved by our proposed algorithm and compared to exhaustive search and different decoding strategies.Back to article page
