Based on the channel measurements at 5.25 GHz in the hotspot area, empirical path loss (PL) models are developed and discussed for the IMT-Advanced system design. The measured scenarios include indoor line-of-sight (LOS), non-LOS, outdoor LOS/obstructed LOS, and outdoor-to-indoor propagations. The PL exponent, intercept, and standard deviation of shadow fading are obtained by using the least square...
MIMO can enhance the performance of wireless system greatly. However, the limited battery life and terminal size of the UE in a cellular system put a constraint on the performance enhancement by MIMO. Especially when the transmitter has more antenna than the receiver in downlink, the conventional MIMO schemes can only exploit partial spatial multiplexing gain and diversity gain. For different users'...
