1. A method of generating an amble sequence in a wireless communication network having a first amble sequence, comprising:
- generating a second amble sequence in a frequency domain having a low cross-correlation with the first amble sequence;
generating a third amble sequence based upon the second amble sequence and having a substantially low to zero cross-correlation with the second amble sequence;
transmitting a pair of the second and third amble sequences with each amble sequence of the pair in an alternating frame of the wireless communication network.

Abstract
The embodiments generate a new type of amble sequence for a wireless communication network with mixed nodes, by generating a first amble sequence invisible to a first node based upon an existing amble sequence for the first node and generating a second amble sequence having a low to zero cross-correlation with the first amble sequence, based upon the first amble sequence. The first and second amble sequences can be broadcast in alternating communication link frames.
