1. Bler performance comparison of RegAE with different drop rates for the M = 4 and R = 1 system and the uncoded BPSK communication model.

2. Supported modes are RTTY (Baudot code), ASCII (7 or 8 bits), PSK31 (BPSK and QPSK), BPSK63, AMTOR-FEC (SITOR-B, NAVTEX), MultiFSK-16, MultiFSK-8.

3. Question: Consider BPSK Modulation, Where Two Antipodal Signals S{(1) = -s1 (1) = /E3, 2 Cos (2A Fet) Tь Are Used For The Transmission Of Equally Likely Bits 0 And 1 Every T Seconds, Respectively

4. A program for amateur radio digital communications via a sound card. Supported modes are RTTY (Baudot code), ASCII (7 or 8 bits), PSK31 (BPSK and QPSK), BPSK63, QPSK63, BPSK125, AMTOR-FEC (SITOR-B, NAVTEX), MultiFSK-16, MultiFSK-8.
