摘要:
In a communication system, a signal transceiver generates an upper pre-encoding symbol stream and a lower pre-encoding symbol stream by pre-encoding an upper transmission vector and a lower transmission vector according to a pre-encoding scheme when the upper and lower transmission vectors to be transmitted are input. The signal transceiver generates a space-time mapping matrix by space-time mapping the upper and lower pre-encoding symbol streams according to a space-time mapping scheme based on the number of transmit antennas to be used in the signal transceiver. The signal transceiver generates and transmits a codeword according to whether a null transmission is present in the space-time mapping matrix.

摘要:
Provided is a composition for in vivo transplantation for the treatment of human cervical cancer, comprising mononuclear cells derived from umbilical cord blood and a pharmaceutically acceptable carrier. When the umbilical cord blood-derived mononuclear cells are transplanted in vivo, cervical cancer can be effectively treated. In particular, the mononuclear cells derived from the umbilical cord blood retain high differentiation and proliferation abilities and exhibit very low graft-versus-host (GVH) reactions which are side effects caused by transplantation, and thus, can be transplanted to many patients.
