Low-bit rate feedback strategies for iterative IA-precoded MIMO-OFDM-based systems
Interference alignment (IA) is a promising technique that allows high-capacity gains in interference channels, but which requires the knowledge of the channel state information (CSI) for all the system links. We design low-complexity and low-bit rate feedback strategies where a quantized version of...
