User can move LEFT/RIGHT keys to select and press ENTER key to confirm. 2K and
8K are the options:
2K: When the device works as current mode, the number of current carrier is 2048
8K: When the device works as current mode, the number of current carrier is 8192
Guard Interval
In communications, guard intervals are used to ensure that distant transmissions do
not interfere with each other. These transmissions may belong to different users (as in
TDMA) or same user (as in OFDM). The purpose of the guard interval is to
introduce immunity to propagation delays, echoes and reflections, to which digital
data is normally very sensitive. There are four possible options provided to be
selected. They are 1/4, 1/8, 1/16, 1/32. User can shift the LEFT/RIGHT keys to select
and press ENTER to confirm.
Code Rate
The code rate includes 1/2, 2/3, 3/4, 5/6, and 7/8. After entering this submenu, the
