Appendix C. OVERHEAD and

SYMBOL RATE CALCULATIONS

C.1

Overview

This appendix applies to both the SLM-5650C and the SLM-5650C-ODU.

The modem has several optional features and functions that can add overhead. This appendix
describes:

•

The processing flow where overhead can be added;

•

The amount of overhead added by each feature when enabled;

•

The calculation of modem symbol rate and modem chip rate (when optional spreading is
enabled), given the programmed modem bit rate.
