Manual Supplement Glossary-3
Forward ChannelA channel transmitted from a base station to mobile stations. The
Forward Channel comprises one or more code channels that are transmitted on a WCDMA
frequency assignment using a particular long code.
InterleavingThe process of reordering code symbols for transmission. Interleaving
decorrelates channel fading between adjacent symbols as they enter the decoder, thereby
improving the effectiveness of the code.
Interrupt TimeThe duration of time during which the data channel is suppressed.
kspsKilosymbols per second (10
3
symbols per second).
Long CodeA maximal length sequence with period 2
41
–1. A unique phase of the long
code identifies each mobile station.
PerchWideband CDMA forward link channel used to establish synchronization with
mobile units.
PN SequencePseudorandom sequence. A periodic binary sequence approximating, in
some sense, a Bernoulli (coin tossing) process with outcomes that are equally probable.
Reverse ChannelThe channel from a mobile station to a base station. From the base
station’s perspective, the Reverse Channel is the sum of all mobile station transmissions
on a frequency assignment.
SDCCHStand-Alone Dedicated Control Channel.
SFNSystem Frame Number.
SFN RSTSystem Frame Number Reset. For more information, see “12. PATTERN TRIG
IN Connector (SystemFrameNumberResetIn)” on page3-13.
Short CodeChannelization code for a WCDMA channel. One of a set of orthogonal
waveforms used as orthogonal cover to create independent transmission channels.
TPCTransmission Power Control. For more information, see “17. EVENT 2 Connector
(Transmission Power Control Out)” on page3-15.
UPCHUser Packet Channel.
WCDMAWideband Code Division Multiple Access. A technique for spread-spectrum
multiple access digital communication that creates channels through the use of noise-like
carriers.
