DESAIN PROGRAM SIMULASI PENERAPAN KODE BOSE CHAUDHURI HOCQUENGHEM PADA DIRECT SEQUENCE SPREAD SPECTRUM

Abstract

This study proposes a design of simulation program for implementing Bose Chaudhuri
Hocquenghem (BCH) code on Direct Sequence Spread Specterum (DSSS) to knowing the
performance of the effect of DSSS with flat fading channel and AWGN without BCH code (7,4)
with the application of BCH code (7,4) on DSSS with flat fading and AWGN channel. This
simulation consist of simulation of BER application of BCH code (7,4) on DSSS with flat fading
and AWGN channel, simulation of BER application code BCH (7,4) on DSSS with AWGN
channel, simulation of the effect of Eb/No on noise variance in the DSSS system, and BER
simulation as a function of noise variance on the DSSS system. Simulation of application BCH
code (7,4) on DSSS with flat fading and AWGN channel analyzed based on Bit Error Rate
(BER) versus Energy Bit per Noise (Eb/No). The application of BCH code (7,4) on DSSS with
flat fading channel and AWGN shows better performance than DSSS with flat fading channels
and AWGN without BCH coding (7,4). On the Eb/No value 10 dB, simulation application BCH
code (7,4) on DSSS with flat fading channel and AWGN generate BER value which is
approaching 0 with BER value 0.0188, while the DSSS simulation with flat fading channel and
AWGN without BCH code (7.4) generate a BER value of 0.0228.
