Coverage prediction in modern cellular systems is usually performed with the aid of a planning tool, using a suitable elevation and terrain digital model (i.e., a database of heights and land usage) and algorithms that estimate basic path loss plus a

We discuss the relative performance of coherent phase-shift keying (PSK), differential PSK (DPSK), and double differential PSK (DDPSK) modulation schemes over a mobile radio channel in which transmission is affected by additive noise, a constant carr

It is pointed out that the future European cellular digital mobile radio system in the 900 MHz band adopts a narrowband time division multiple access (TDMA) scheme with Gaussian minimum-shift keying (GMSK) modulation and burst type transmission. Cons
