Block Error Rate
CDMA
Code Division Multiple Access.
A wideband spread spectrum technique used in digital cellular, personal communications
services, and other wireless networks. Wide channels (1.25 MHz) are obtained through
spread spectrum transmissions, thus allowing many active users to share the same
channel. Each user is assigned a unique digital code, which differentiates the individual
conversations on the same channel.

dB
Decibel = 10 x log
10
(P1 / P2)
P1 is calculated power; P2 is reference power
Decibel = 20 x log

10
(V1 / V2)
V1 is calculated voltage, V2 is reference voltage
dBm
A logarithmic (base 10) measure of relative power (dB for decibels); relative to
milliwatts (m). A dBm value will be 30 units (1000 times) larger (less negative) than a
dBW value, because of the difference in scale (milliwatts vs. watts).
