Assuming application of the received signal estimation method at an arbitrary remote location, we evaluate eavesdropping performance against the secret key agreement technique based on radio propagation characteristics. In the technique, key agreement is realized utilizing the locality of multipath fading. The locality can be broken by using the received signal estimation method and the possible range...
A 60GHz-band compact-range wireless access system using a large array antenna can provide an uniform signal reception zone (less than 14 m distance from the antenna) and an almost multipath-free propagation environment. To evaluate the system performance, a wireless communication system for demonstration is constructed and the bit error rate (BER) and the signal-to-interference-plus-noise ratio (SINR)...
