Simulation Estimation of the Forward Error Correction of Turbo Codes

Error correction techniques play an important role in making wireless communications ever the more efficient and reliable. In order to have reliable communications, channel coding is often employed. Turbo code as a powerful coding technique has been widely studied and used in communication systems. The performance of turbo code used in Code Division Multiple Access 2000 (CDMA) under AWGN channel and Binary Phase Shift Keying (BPSK) is evaluated. The bit error rates (BER) of turbo code at low signal-to-noise ratio (SNR) are obtained by simulations.
