Abstract:
A method of determining reserved tones to be used for reduction of a peak to average power ratio (PAPR) of a signal includes: randomly selecting carrier indices for the reserved tones and generating a kernel signal based on the randomly selected carrier indices; calculating a comparison reference average value of the kernel signal, comparing the calculated comparison reference average value with a prestored comparison reference average value, and preliminarily determining carrier indices of the reserved tones based on the comparison; randomly re-arranging an order of the preliminarily determined carrier indices of the reserved tones; and calculating the comparison reference average value while changing each of the re-arranged indices of the reserved tones, and finally determining carrier indices for which the calculated comparison reference average value becomes the smallest value as carrier indices of the reserved tones.

Claim (Index 1):
A receiving apparatus comprising:\n a receiver configured to receive a frame comprising an orthogonal frequency division multiplexing (OFDM) symbol from a transmitting apparatus; and a processor configured to process the received frame based on positions of reserved tones for reducing a peak to average power ratio (PAPR) reduction, wherein a fast fourier transform (FFT) size of the OFDM symbol is 32K, and wherein the positions of reserved tones are represented by a set of carriers having carrier indices listed below: FFT Size (Number of Reserved Tones) Carrier Indices 32K 803, 805, 811, 901, 1001, 1027, 1245, 1258, 1318, 1478, 1507, 1509, 1556, 1577, 1655, (288) 1742, 1978, 2001, 2056, 2110, 2164, 2227, 2305, 2356, 2408, 2522, 2563, 2780, 2805, 2879, 3010, 3019, 3128, 3389, 3649, 3730, 3873, 4027, 4066, 4087, 4181, 4246, 4259, 4364, 4406, 4515, 4690, 4773, 4893, 4916, 4941, 4951, 4965, 5165, 5222, 5416, 5638, 5687, 5729, 5930, 5997, 6005, 6161, 6218, 6292, 6344, 6370, 6386, 6505, 6974, 7079, 7114, 7275, 7334, 7665, 7765, 7868, 7917, 7966, 8023, 8055, 8089, 8091, 8191, 8374, 8495, 8651, 8690, 8755, 8821, 9139, 9189, 9274, 9561, 9611, 9692, 9711, 9782, 9873, 9964, 10011, 10209, 10575, 10601, 10623, 10690, 10967, 11045, 11083, 11084, 11090, 11128, 11153, 11530, 11737, 11829, 11903, 11907, 11930, 11942, 12356, 12429, 12484, 12547, 12562, 12605, 12767, 12863, 13019, 13052, 13053, 13167, 13210, 13244, 13259, 13342, 13370, 13384, 13447, 13694, 13918, 14002, 14077, 14111, 14216, 14243, 14270, 14450, 14451, 14456, 14479, 14653, 14692, 14827, 14865, 14871, 14908, 15215, 15227, 15284, 15313, 15333, 15537, 15643, 15754, 15789, 16065, 16209, 16213, 16217, 16259, 16367, 16369, 16646, 16780, 16906, 16946, 17012, 17167, 17192, 17325, 17414, 17629, 17687, 17746, 17788, 17833, 17885, 17913, 18067, 18089, 18316, 18337, 18370, 18376, 18440, 18550, 18680, 18910, 18937, 19047, 19052, 19117, 19383, 19396, 19496, 19601, 19778, 19797, 20038, 20357, 20379, 20455, 20669, 20707, 20708, 20751, 20846, 20853, 20906, 21051, 21079, 21213, 21267, 21308, 21355, 21523, 21574, 21815, 21893, 21973, 22084, 22172, 22271, 22713, 22905, 23039, 23195, 23303, 23635, 23732, 23749, 23799, 23885, 23944, 24149, 24311, 24379, 24471, 24553, 24585, 24611, 24616, 24621, 24761, 24789, 24844, 24847, 24977, 25015, 25160, 25207, 25283, 25351, 25363, 25394, 25540, 25603, 25647, 25747, 25768, 25915, 25928, 26071, 26092, 26139, 26180, 26209, 26270, 26273, 26278, 26326, 26341, 26392, 26559, 26642, 26776, 26842
