Performance on BCH and Convolutional Codes in Direct Sequence Spread Spectrum Packet Radio Networks

Abstract

The performance of forward error correction codes has been well documented in the open literature when the noise is additive, white, and Gaussian. Little or no work exists on the performance of forward error correction codes when the noise is due primarily to multiple access interference. In this paper, we examine the performance of BCH and convolutional codes in a direct-sequence spread spectrum packet radio network. Packet errors are caused by a combination of noise at the receiver and interference between packet transmissions which overlap in time. The interference between packet transmissions produces dependent symbol errors at the output of the demodulator. In our work, we compute first an upper bound on the symbol error probability. Then we use this upper bound to calculate upper bounds on the packet error probability for both BCH and convolutional codes. Our results enable us to compare the performance of BCH and convolutional codes in the presence of multiple access interference.
