Spread Spectrum Techniques with Channel Coding for Wideband Secured Communication Links

Ultra-wideband (UWB) radios provide avenues for interference immunity using spread spectrum (SS) techniques. Doing so, provides a processing gain of 21 dB, allowing for successful retrieval of signals propagated below the noise floor. In addition, by applying advanced channel coding an additional coding gain of 9 dB can be achieved. In this paper, we are exploiting SS techniques with channel coding to maximize gain in wireless communication links. Bit error rate (BER) performance is presented for multiple channel coding approaches.
