Direct Sequence Spread Spectrum (FAST Option)

As On-The-Move systems with very small dishes (e.g., VSATs) become more popular, there is an
increased interest in Spectrum Spreading. To meet this need,

(

DSSS

) is optionally available in the SLM-5650B.

DSSS works by modulating the normal carrier with a pseudo-random PN sequence (chips) at a
much higher chip rate. The chip rate is determined by the carrier’s symbol rate and a multiplying
(spreading) factor.

The SLM-5650B offers spreading in the following LDPC MODCODs:

ULL
BPSK
1/2

LL
BPSK
.378

LL
BPSK
.451

LL
BPSK
.541

HP
BPSK
1/3

HP
BPSK
1/2

The Spreading Factors currently supported are 1(Spreading Off), 2 through 512 up to a maximum
chip rate of 64 Mcps. The user can select between two built-in pseudo-random PN sequences
(polynomials) and 10,000 Gold Code Sequences per polynomial so that multiple spread carriers
can occupy the same bandwidth in a Code-Division Multiple Access (CDMA) fashion.

When using large spreading factors, the SLM-5650B also exhibits a large tolerance to jamming –
up to 24 dB – and a Low Probability of Detection/Interception. With DSSS enabled, the lower data
rate limit has been reduced to 8 kbps. The SLM-5650B Base Modem Web Server Interface
provides a Web page to facilitate anti-jamming applications. This page allows the user to
configure the modem parameters so that a fixed occupied bandwidth can be maintained.

Lastly, there is no loss in performance with spreading enabled.
