A practical precoder design for EST-based modulation in frequency-selective channel

In this paper, a practical precoder for EST-based modulation to obtain transmit diversity in frequency-selective channel is considered. First, we design the finite impulse response (FIR) filter based matched filter bound (MFB) as precoder at the transmitter. Then the criterion which evaluates the overall performance of EST-based iterative receiver and adjust the length of FIR filter is proposed.
