摘要:
A method and apparatus for transmitting and receiving a signal in a wireless communication system. The wireless communication system includes a transmitter with at least four transmit antennas and a receiver with at least one receive antenna. Space Frequency Block Coding (SFBC) processes are performed for input signals on a basis of two antenna pairs. Signal blocks whose number corresponds to the number of transmit antennas are output. A Space Time Block Coding (STBC) process is performed for the signal blocks generated according to the antenna pairs. Signals carried by single carriers are transmitted through the at least four transmit antennas mapped to the signal blocks.

The present invention relates to a method of peptide sequencing by MALDI (matrix-assisted laser desorption ionization) tandem mass spectrometry, which comprises the steps of chemically modifying a sample peptide with at least one chemical modification method selected from the group consisting of guanidination and esterification in order to change the ionization status of the peptide and performing mass spectrometry using a MALDI tandem mass spectrometer and programmed MALDI tandem mass spectrometry. The peptide sequencing method of the present invention is advantageous in that detection sensitivity of the peptide improves significantly and various daughter ions are detected uniformly, thereby enabling perfect de novo sequencing with tandem mass spectrometry only, without database search.

The present invention relates to a plastic photonic crystal fiber for terahertz wave transmission and a method for manufacturing thereof. More particularly, the present invention is directed to a plastic photonic crystal fiber which can be easily maunfactured and has low loss characteristics to be used as a waveguide of teraherzt waves. The plastic photonic crystal fiber includes a crystal defect component having a longitudinal axis and a photonic crystal component surrounding the crystal defect component. The photonic crystal component has an array of a plurality of plastic elements having logitudinal axes and forming a 2 dimensional photonic crystal structure with a predetermined lattice constant. Further, the plastic photonic crystal fiber of the present invention can be used as a preform from which a plastic photonic crystal fiber for an optical communication (400-800 nm) can be drawn.
