Antenna design for 2.4 GHz ISM band
The utilization of 2.4 GHz ISM band has experienced enormous growth in the last 5 years. A lot of research has been conducted on the design of antennas operating inside this band. The limited space on the circuit board for the RF module imposes a limit on the physical size available for the …

A Model-Based Approach to Demodulation of Co-Channel MSK Signals
… operating in unlicensed bands such as the 2.4 GHz ISM band and for narrowband systems that have been overlaid with spread spectrum systems. In this work we have developed model-based techniques for the demodulation of co-channel MSK signals. It is shown that MSK signals can be written in the …

Radio frequency ranging for wireless sensor network localization
… of their position and thus a localization mechanism is often a requirement. The process of localizing a 'blind' device consists of ranging estimates or angle measurements to a set of references with a prior knowledge of their position relative to a co-ordinate system and the position computation …
