Telemetry Transmitter

Quasonix, Inc.

The IRIG standard calls out six variants of LDPC codes

—

all combinations of two different information block sizes

(k=4096 bits and k=1024 bits) and three different code rates (r=1/2, r=2/3, and r=4/5).

LD6 Code

Block Size and Code Rate

k=4096, r=1/2

k=1024, r=1/2

k=4096, r=2/3

k=1024, r=2/3

k=4096, r=4/5

k=1024, r=4/5

With the LD6 option

, use LD 0 or 1 to disable or enable LDPC, then use 0-5 to indicate the desired LDPC code. A

space is required between the disable/enable code and the desired LDPC selection, as shown in the examples.

Examples:

LD 0

Disable the LDPC encoder

LD 1 0 Enable the LDPC encoder and set the block size and code rate to k=4096, r=1/2

LD 1 1 Enable the LDPC encoder and set the block size and code rate to k=1024, r=1/2

LD 1 2 Enable the LDPC encoder and set the block size and code rate to k=4096, r=2/3

LD 1 3 Enable the LDPC encoder and set the block size and code rate to k=1024, r=2/3

LD 1 4 Enable the LDPC encoder and set the block size and code rate to k=4096, r=4/5

LD 1 5 Enable the LDPC encoder and set the block size and code rate to k=1024, r=4/5

4.2.3.1.5 LDPC Header Select

–

LHS

The LHS command sets the header to use with Low Density Parity Check (LDPC) coding on a transmitter. Valid
settings are 0 through 6, however code 6 is for Quasonix internal use only.

0 - SOQPSK/LDPC code 0

0 // LDPC k=4096 r=1/2

1 - SOQPSK/LDPC code 1

1 // LDPC k=1024 r=1/2

2 - SOQPSK/LDPC code 2

2 // LDPC k=4096 r=2/3

3 - SOQPSK/LDPC code 3

3 // LDPC k=1024 r=2/3

4 - SOQPSK/LDPC code 4

4 // LDPC k=4096 r=4/5

5 - SOQPSK/LDPC code 5

5 // LDPC k=1024 r=4/5

6 - iNet test code 6 (Quasonix internal)

6 // inet M.R. test
