Abstract

In this paper, we propose a scaled cyclic delay diversity (SCDD) based precoding for coded multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. In order to improve the bit error rate (BER) performance, the proposed precoding reduces the maximum correlation of the precoded channel in frequency domain. In addition, a decision criterion for the scaling factor is suggested by analyzing the bit error probability of repetition codes, convolutional codes, and turbo codes. We present the simulation results for the BER performance to verify the effect of proposed SCDD-based precoding.
