Performance of Intercode Interleaving in the Indoor Portable Radio Channel
نویسندگان
چکیده
This paper examines the performance by simulation of an intercode interleaving technique, for indoor portable radio channels. The intercode interleaving technique is implemented by placing a bit interleaver between two concatenated BCH codes. The modulation used is d4-shifted DQPSK, with differential detection. The envelope and phase fading in the quasi-static indoor radio channel is modeled by SIRCIM [l]. The cochannel interference is modeled by independently faded n/4-shifted DQPSK interferences. For the power-limited channel, it is observed that intercode interleaving offers significant gains over uncoded modulation in terms of block error rate.
