Abstract A segmented maximum likelihood iterative detection algorithm is proposed for distributed space- frequency coded cooperative communication system with multiple relay nodes over frequency-selective fading channels. The destination node divides each distributed space-frequency coding vector into several sub-segment evenly in frequency domain, and performs maximum likelihood detection on them respectively. Theoretical analysis and simulation results confirm the fast convergence speed, the low complexity and the high practicality of the proposed iterative detection algorithm.
