| Abstract(in English) | Recently, we proposed the space-frequency codes employing Weyl groups which extend the number of codewords of the diagonal space-frequency codes in. However, we did not take account of the Peak-to-Average Power (PAPR). Therefore in this paper, we propose shift repetition space-frequency codes with low PAPR. The proposed codes are investigated by computer simulations. As the results, the 4-shift two-repetition proposed code shows about 2dB coding gain and reduces PAPR by half compared with O-shift two-repetition code for equal power two-ray channel model. Also, the code displays about 4dB coding gain compared with no-repetition code at the cost of the spectral efficiency. |
