Abstract
Carrier frequency offset (CFO) estimation is effected by transmission of contemporaneous bit patterns, detectable by a receiver. By analysis of periodicity of bit error occurrences at the receiver, a beating period caused by interference between the two transmitters can be identified. From this beating period, a measure of CFO can be obtained.
