    • The present invention relates to tricarbonyl technetium-99m or rhenium-188 labeled cyclic RGD derivatives, a preparation method thereof, and a pharmaceutical composition containing the derivative as an active ingredient for use in the diagnosis or treatment (radiotherapy) of angiogenesis-related diseases. The tricarbonyl technetium-99m or rhenium-188 labeled cyclic RGD derivatives of the present invention has a high subnanomolar affinity to integrin αvβ3 (also called as a vitronectin receptor) that is activated in an angiogenic action induced by a tumor, reflects a high tumor image of the tricatvonyl technetium-99m labeled cyclic RGD derivative after initial intake in an animal in which cancer cells are transplanted, and acts exclusively upon cancer cells having selectively activated integrin αvβ3 because of a substantially low intake into the liver and intestines, compared to existing known radioactive isotope labeled cyclic RGD derivatives. These results show that the rhenium-188 labeled derivative, a therapeutic nuclide using the same precursor as used in the technetium-99m labeling, effectively inhibits the growth of a tumor and demonstrates therapeutic efficacy when administered via tail vein injection to an animal model bearing tumor, compared to a case where only saline has been injected, thereby making it useful as a medicine for the diagnosis or treatment of angiogenesis-related diseases.

    • Disclosed are a signal distortion component adjusting apparatus and method capable of adjusting error vector magnitude of subcarriers of a predetermined position by adjusting a signal distortion component occurring while decreasing a peak to average power ratio (PAPR) in a communication system of an orthogonal frequency division multiplexing (OFDM) technology or an orthogonal frequency division multiple access (OFDMA) scheme, and a system using the same. The present invention includes a signal distortion component adjusting unit to add an additional signal distortion component Pe((n+N/2) % N) to a signal distortion component e(n) that is obtained by subtracting a threshold Th value, set to decrease peak power, from an absolute value of a time domain signal x(n) of an input signal, and to thereby adjust the signal distortion component. The present invention may transmit a highly reliable signal by adjusting error vector magnitude of subcarrier of a frequency domain.
