商品簡介
This engineering handbook introduces the two most common modulation technologies used in standardized consumer communication networks--direct sequence spread spectrum (DSSS) and orthogonal frequency division modulation (OFDM)--the principle of multicarrier phase measurement, methods of relating distance to received signal strength, and the geometric use of distance measurement to determine location. The application chapters describe cellular networks, short-range wireless networks, RFID tags, and ultrawideband systems. The second edition adds chapters on global navigation satellite systems and complementary technologies. Annotation c2016 Ringgold, Inc., Portland, OR (protoview.com)
