Abstract
A method of operation of a wireless communication system includes: receiving a received signal; generating concurrently a first modulation data and a second modulation data from the received signal; calculating an error energy for the first modulation data and the second modulation data; and removing a residual Direct Current (DC) offset from the received signal based on determining a minimum of the error energy for the first modulation data or the second modulation data.
