I am designing a channel encoder (BCH/RS/Turbo) + Modulator based digital communication system in simulink.

My blocks in the design are

1) Ber. B. Gen/Ran Int Gen
2) BCH (15,7) or RS (255,223) Encoder & Decoder
3) QPSK/M-ary PSK Mod & De Mod
4) AWGN Channel

the problem i am facing is the input to the modulator/demodulator should be in terms of multiples of bits (even) but the outputs/inputs from/to the channel encoder/decoder are in odd number. i am unable to fix this error.

also, kindly give your inputs in using bit to integer/integer to bit generator so that they can be connected to modulators and channel encoders

kindly give your inputs
 

try using a buffer/unbuffer whose size is an even multiple of the size of the encoder/decoder
