hi all can any body help out. in joining DCL and Viterbi decoder
  i am trying to design a BPSK demodulator in matlab.i have used Digital costas loop(DCL) and
its working fine.my program flow is like this..
   
  Message--> 1/2FEC--> Interpolation(only for simulation) --> BPSK modulation --> 
     AWGN Addition --> 
  DCL (Demodulation)--> Decimation --> 3-Samples Per Bit ------  XXX ---->   Viterbi
Decoder
   
  i am able to work with viterbi individually, its decoding perfectly.
  my  problem is, Science i have 3 sample at the out put of my DCL i cant directly give it to
viterbi. Even if i give it to it its showing incorrect results.
   
  what should i do to now, ????????/
  regards
