1. A method comprising:
- generating a legacy long training symbol (LTS) at a transmit processor, wherein the legacy LTS comprises a first plurality of subcarriers;
generating an extended LTS, wherein the extended LTS comprises a second plurality of subcarriers, wherein the first plurality of subcarriers has fewer subcarriers than the second plurality of subcarriers, wherein the extended LTS comprises the legacy LTS, and wherein the generating the extended LTS comprises inserting additional subcarriers at spectral band edges of the legacy LTS; and
transmitting the extended LTS.
