MPEG Moving Picture Experts Group
M-QAM M-order of Quadrature Amplitude Modulation
MRC Microwave Radio Communications
Multipath An unpredictable set of reflections and/or direct
waves, each with its own degree of attenuation and
delay. Due to obstacles and reflectors in the wireless
channel, transmitted signals arrive at the received
from various directions over multiple paths.
MUX Multiplexer
NC Normally Closed (Relay or switch contacts)
N/C No Connection
NICAM Near-Instantaneous Companding and Multiplexing
NO Normally Open (Relay or switch contacts)
NRZ Non-Return-to-Zero (Modulation)
NTSC National Television System Committee
Color television standard used in the US. Provides
525 horizontal lines of resolution. Not compatible with
PAL or SECAM.
Null modem
cable
An RS-232 cable designed to connect two computers
(or other data sources) together. It has male DB9
connectors on each end, to mate with the DB9
female connectors on the PCs. It also has the
Transmit and Receive connections crossed over so
Transmit (pin 3) on one end connects to Receive (pin
2) on the other.
Also called “Crossover Cable”.
ODU Outdoor Unit
OFDM Orthogonal Frequency Division Multiplexing
OOK On-Off Keying

PAL Phase Alteration Line
Color television standard used in many European
countries. Provides 625 horizontal lines of resolution.
Not compatible with NTSC or SECAM.
PAL-M Phase Alteration Line
Color television standard used in many European
countries. Provides 625 horizontal lines of resolution
with 50 lines per field. Not compatible with NTSC or
SECAM.
PAL-N Phase Alteration Line
Color television standard used in many European
countries. Provides 525 horizontal lines of resolution
with 60 lines per field. Not compatible with NTSC or
SECAM.

PRBS Pseudo Random Bit Sequence
QAM Quadrature Amplitude Modulation
QPSK Quadrature Phase Shift Keying
The signal (video+audio) is imposed onto the 70 MHz
carrier by varying the phase of the signal while
keeping the amplitude and frequency constant. There
are 4 possible values of phase that can be used to
carry information.
