Abstract—2×2 unitary precoding based on receiver feedback is applied alongside spatial multiplexing at the base station in HSDPA (D-TxAA) when the mobile terminal supports MIMO transmissios [1]. This precoding will influence achievable sumrate

Adaptive equalization教程-Adaptive equalizers compensate for signal distortion attributed to intersymbol interference (ISI), which is caused by multipath within time-dispersive channels. 􀂃 Typically employed in high-speed communication
