Personal communications services: improving theater deployable communications for the 21st century
Personal Communications Services (PCS) may be the key ingredient for vastly improved military communications capabilities at the turn of the century. The Federal Communications Commission (FCC) defines PCS as a family of mobile or portable radio communications services which could provide services …

A correlation-based method for direction finding of multipath signals in frequency hopping systems
… be larger than the number of signal sources. In military communications and some short-range wireless communication systems (e.g. Blue-tooth), frequency hopping technique is widely used. In such systems, it is difficult to equip a large size antenna array. Therefore, it is necessary to solve the …
