This paper introduces linear constellation precoding (LCP) for OFDM transmissions over frequency-selective fading channels. Exploiting the correlation structure of OFDM subchannels, and choosing system parameters properly, we first perform op

In this paper, we study Spatial Tomlinson-Harashima Precoding (STHP). We propose a generalization of the original structure of STHP which enables different transmission power per antenna. The main advantage of the new scheme is that it has a

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
