For broadband wireless systems, the channel between the transmitter and the receiver exhibits frequency selectivity in nature. In this paper, an Finite impulse response (FIR) precoder which supports multiple streams at the transmitter and an FIR minimum mean-squared-error decision feedback equalizer (MMSE-DFE) at the receiver are jointly designed for broadband multi-input multi-output (MIMO) multicast...
Finite impulse response (FIR) precoders are efficient precoding framework for frequency-selective multiple-input multiple-output (MIMO) channels. In this paper, the optimal linear FIR precoder is investigated to maximize the capacity of frequency-selective MIMO channel under average transmit power constraint. We use Kronecker product to regenerate the nonconvex optimization problem and propose a semidefinite...
