Bit and symbol error rates for complementary code key modulation with alternative bit mappings

Full-rate modulation in the IEEE 802.11b standard employs complementary code keying (CCK) with a set of 256 signals that provides 11 Mb/s in favorable indoor propagation environments. The bit-to-symbol mapping of IEEE 802.11b is suboptimal for applications in which the bit error probability is important. We present analytical and simulation results on the bit and symbol error probabilities for IEEE 802.11b CCK and alternative bit mappings that improve CCK systems that need not adhere to the standard.
