Embodiments of the present invention may help facilitate improved performance for high throughput, mobile wireless networks, e.g., IEEE 802.16m, mobile implementations for 3GPP Long Term Evolution (LTE) including LTE advanced mobile phone networks, and other types of high bandwidth networks. In some embodiments, provided are orthogonal sequences with desirable correlation properties for, e.g., 4-6 bits of information, among other things, typically achieving improved performance at varied vehicle speeds. In some embodiments, correlation distances for 6 bits may be less than 3.86, for 5 bits may be less than 3.12, and for 4 bits may be less than 1.95. Additionally, in some embodiments, dedicated coding for PFBCH information may be provided to achieve improved performance for most (if not all) information bits at a relatively wide range of vehicle speeds. Different code sequences for different tiles in one PFBCH channel may be applied for same messages to overcome error floors in high speed scenarios.
