In this paper, we propose a new single-input multiple-output (SIMO) context-aware cognitive transceiver (CTR) that is able to switch to the best performing modem in terms of link-level throughput and allows to decrease macro transmission power without loosing performances comparing to the conventional Data-aided Least Squares (DA LS) channel estimator. On the top of conventional adaptive modulation...
Deploying small cells (pico, femto or relays) in a macro-cell network is an advantageous solution to increase system capacity. However, small cells usually transmit with a weaker power compared to macro-cells, this fact causes a serious interference problem for these former. Range Expansion technique is among the solutions proposed to overcome this problem. The idea is to bias the received signal...
