Abstract :
The joint Cramer-Rao Bound (CRB) of carrier frequency offsets (CFO) and channel Impulse responses (CIR) are derived in this paper to verify the Maximum-Likelihood (ML) estimation performance for multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) coordination on multiple point (CoMP) systems in this paper. The simulation results verify the theory analysis:ML performance doesn´t approach CRB well for CoMP system because the orthogonality loss because of CFOs and CIRs.
