In this paper, we propose a low-cost compensation scheme for IQ imbalance using only one pilot symbol for an orthogonal frequency division multiplexing (OFDM) based digital radio mondiale (DRM)system, planned to operate in FM bands. Since the existing methods require more than one OFDM symbol, this scheme is more efficient in computation, yet performs as well as the existing scheme.
