+-------------------------
Two users are transmitting simultaneously using convolutionally encoded QPSK, each with power P1=alpha*P and P2=(1-alpha)*P.
The combined signal is observed in noise and four different receivers are considered:
1) A viterbi decoder decoding user 1 assuming user 2 is noise
@@ -13,4 +15,18 @@ The combined signal is observed in noise and four different receivers are consid
You can change the signal to noise ratio P/sigma^2 and the allocation of power to the two users, alpha.

+Serially Concatenated Convolutional Codes
+-----------------------------------------
+An SCCC can be defined by an outer and an inner FSM together with an interleaver
+and a modulation type. You can change the SNR and observe the estimated BER.
+In sccc.grc the decoding and metric calculation are combined; in sccc1.grc they are separate.
