Optimal Training Signals Design for MIMO-OFDM

Broadband MIMO-OFDM channel models were derived.The Bayesian CRB and Bayesian MMSE of non-blind channel estimation was derived under spatial correlation circum- stances.The power of training sequences that minimize the channel estimation Bayesian CRB was allocated.A Linear Programming(LP) method was used for optimal power distribution design and the transmit unitary matrix was used for optimal phase design in MIMO-OFDM systems with guard subcarriers.
