Abstract
This paper analyses the estimation of residual frequency offset in MIMO OFDM systems using pilot subcarriers. A closed-form expression for the MSE is derived and this is used to study the pilot design problem. An orthogonal design is proposed and simulation results show that this is superior to using the same pilots on all pilot subcarriers
