This paper investigates a tradeoff between the peak-to-average power ratio (PAPR) and channel capacity of the proposed PAPR reduction method based on clipping and filtering (CF) for precoded multiple-input multiple-output (MIMO)- orthogonal frequency division multiplexing (OFDM) transmission in a frequency-selective faded channel. While the conventional CF method adds roughly the same interference...
This paper addresses the margin adaptive (MA) problem in MIMO OFDMA multi-cell networks, when the transmitter only has statistical channel state information. Resource allocation is distributed within each base station. A distributed convergence criterion for power control is determined and included within iterative power allocation. An approximate analytical expression is obtained for the outage capacity,...
LTE-advanced system which based on orthogonal frequency division multiplexing (OFDM) can eliminate intra-cell interference but still can not mitigate inter-cell interference (ICI). In this paper, we propose a novel cooperative multi-cell multiple-input multiple-output (MIMO) scheme for LTE-advanced system to reduce ICI and improve the cell capacity. By sharing information such as data and channel...
This paper studies a balanced power allocation scheme to approach the capacity limits and power consumption reduce simultaneously of orthogonal-frequency- division-multiplexing multiple-input multiple-output (OFDM-MIMO) channels under the assumption that perfect channel state information (CSI) is available at both the transmitter and the receiver. In this paper, we build a function to describe the...
