+These are examples of using gr-trellis in grc.
+
+INTERFERENCE CANCELLATION
+-------------------------
+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
+2) A viterbi decoder decoding user 2 assuming user 1 is noise
+3) A viterbi decoder decoding user 1 first
+ and then reencoding this signal, subtracting it from the observation
+ and then running a Viterbi decoder decoding user 2
+4) A viterbi decoder decoding user 2 first
+ and then reencoding this signal, subtracting it from the observation
+ and then running a Viterbi decoder decoding user 1
+
+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.
+
+Parallel Concatenated Convolutional Codes
+-----------------------------------------
+A PCCC can be defined by two FSMs together with an interleaver
+and a modulation type. You can change the SNR and observe the estimated BER.
+In pccc1.grc the decoding and metric calculation are separate.
+
+
+Enjoy.
