Mobile channel characteristics /
Mobile Channel Characteristics introduces the principal transmission phenomena of mobile and personal communication - the ones that affect design of modems, channel simulators, smart antennas, and other system components at the physical level. It is designed to be accessible to senior undergraduates...
