In a telemetry system, it has been frequently proved that multipath channels and transmission
noise are the most critical sources of distortion. While equalization allows a strong limitation of
the multipath effects, the noise impact can be efficiently reduced if forward error correction is
used. This paper proves that the combination of blind equalization and a powerful FEC like
LDPC strongly improves bit error rates for the SOQPSK modulation. We also prove that a LDPC
code is able to fully correct the residual errors that may persist at the equalizer output. In other
terms, the combination of equalization and LDPC code enables quasi-error free transmissions in
various channel scenarios that represent the various phases of a telemetry mission.
