Evaluation of OFDM-MIMO Systems Using Convolution with CPM

Guowei Lei, Sunqing Su
Abstract—Orthogonal frequency division multiplexing (OFDM) is regarded as a popular technique. Moreover, OFDM combined with multiple-input multiple-output systems (MIMO) has drawn many interests. However, OFDM-MIMO systems with continuous phase modulation have not been investigated extensively to date. In this paper, we propose an OFDM-MIMO system using convolution codes with continuous phase modulation (CPM). In the system, an interleaver is added between encoder and modulator. Moreover, iterative decoding and demodulation are combined together at receiver. To evaluate the performances, the comparisons between CPM and linear modulations in terms of bit error rate (BER), peak-to-average power ratio (PAPR) and power spectrum density (PSD) are given in the end.

Index Terms—OFDM, MIMO, continuous phase modulation, interleaver.
