Energy detection of Frequency Shift Keying (FSK) signals is one of the non-coherent detection methods for digital FM signals and is usually used when carrier phase estimation is difficult. It is available both for coherent and non-coherent FSK signals. However, as it contains nonlinear modulation and demodulation operation, there have been almost no study in which the energy detection of FSK signal is applied for MIMO frequency selective channels. In this paper, we have proposed to apply the linear equalization method of FDE (Frequency Domain Equalization) with CP (Cyclic Prefix) to the nonlinear FSK modulation. Through this technique, we can achieve the antenna signal separation and equalization simultaneously in frequency domain, and we can use M-FSK signals on MIMO frequency selective channels. Furthermore, by generating the bit LLR from the energy detector output, we have made LDPC decoding to obtain better BER characteristics. |
