A complete complementary code composed of 4phase perfect (orthogonal) sequences is shown. The sequences compose a matrix whose cube is a unit matrix. A method is also discussed, which has been proposed by Suehiro, et.al. for increasing the efficiency of the wireless frequency usage. The method uses a pilot signal for measuring the multipath property as a complex number for each timeslot. The da...

This correspondence presents entropy analyses for dithered and undithered quantized sources. Two methods are discussed that reduce the increase in entropy caused by the dither. The first method supplies the dither to the lossless encoding-decoding scheme. It is argued that this increases the complexity of the encoding-decoding scheme. A method to reduce this complexity is proposed. The second m...

We describe a new approach based on pattern matching for lattice parameter measurements using convergent beam electron diffraction (CBED). Theoretical CBED patterns are calculated using the Bloch wave method. Both experimental and theoretical patterns are processed to enhance the geometric features, and then compared using correlation. By including the dynamic and thickness effects in the simul...

PURPOSE The authors directly compared 3 frequently used methods of heart-rate-based training-intensity-distribution (TID) quantification in a large sample of training sessions performed by elite endurance athletes. METHODS Twenty-nine elite cross-country skiers (16 male, 13 female; 25 ± 4 y; 70 ± 11 kg; 76 ± 7 mL · min-1 · kg-1 VO2max) conducted 570 training sessions during a ~14-d altitude-t...
