Abstract
In an example method, a first device determines a first Zadoff-Chu sequence having a first root value, and a second Zadoff-Chu sequence having a second root value, where the second root value is an inverse modulus of the first root value. Further, the first device generates a wireless signal including (i) a first preamble generated based, at least in part, on the first Zadoff-Chu sequence, (ii) a second preamble generated based, at least in part, on the second Zadoff-Chu sequence, and (iii) a payload. Further, the first device transmits the wireless signal from the first device to a second device.
