Packet error probabilities in direct sequence spread spectrum packet radio networks with BCH codes

The author computes an upper bound on the packet error probability induced in direct-sequence spread-spectrum networks, when BCH codes are used for the encoding of the packets. The bound, which is introduced, is valid independently of whether signals arrive with equal or unequal powers at the receiver site. Furthermore, it has a simple form and is easy to compute. In addition, it is valid for other classes of forward error correction codes (e.g., convolutional codes). However, numerical results are presented for BCH codes only
