In this paper we focus on minimizing the long-term average power consumption of a single transmitter providing Quality of Service (QoS) enabled traffic to a single receiver. Both the transmitting and receiving stations are equipped with multiple antennas. First, we present a general {Kx M} system model where K is the number of independently buffered QoS streams and M is the number of parallel channels...
In this paper, a novel analytical model structure for wideband multiple-input multiple-output (MIMO) channel is presented. It is based on the power coupling between direction of departure (DoD), direction of arrival (DoA) and delay domain. As its realizations, firstly the singular value decomposition (SVD) based model is introduced and the virtual presentation model is extended to the wideband situation...
Some communication applications, like multimedia, deliver data of different importance classes allowing unequal error protection (UEP) levels. In this paper, a multiple-input multiple-output (MIMO) system using orthogonal frequency division multiplexing (OFDM) is considered with a new UEP bit-loading algorithm based on the non-UEP algorithm by Chow, Cioffi, and Bingham. In the proposed bit-loading...
