This paper proposes a robust beamforming scheme under steering vector uncertainty for cognitive radio based vehicular communication. The service probability of secondary users (SU) is maximized, the SU's transmission power is uniform within the target mobility range, and the probability of interference level to primary users (PU) is constrained. Simulation results show significant BER improvement for PU without trading off the SU's performance when there are errors in steering vectors.
