The ever increasing dynamic range requirement for the RX path and maximum transmission power requirement for the TX path add difficulty in the Bluetooth transceiver design. The tradeoff between noise and linearity performance is carefully examined to meet the RX dynamic range requirement. RX anti-interference performance is improved by careful system level planning. TX non-idealities are addressed...
In many circumstances, it is necessary for a node in a Wireless Sensor Network (WSN) to be aware of its location in the physical world. For example, tracking or event-detection functions are not useful if the WSN cannot provide any information where the event has happened. Some location procedures have been proposed in the IEEE 802.15.4a standard, including the time of arrival (TOA) estimation, the...
Perfect channel state information (CSI) is always assumed in work on multiple-input, multiple-output (MIMO) precoding theoretical analyze. In this paper, we investigate the effect of imperfect channel state information on the performance of MIMO broadcast channel (MIMO-BC). We show that even with moderate channel estimation error, the system performance degrade significantly. So, we propose a Frobenius...
