A shared frequency transmitter for use in a network environment where transmitters and receivers of plural radio communication systems in which the same frequency is used exist is disclosed. The shared frequency transmitter includes (a) a communicating unit configured to detect peripheral transmitters existing in a peripheral area, and to exchange information with the detected peripheral transmitters; and (b) a signal generating unit configured to generate a transmit signal by applying an interference cancellation technique based on the information obtained through the exchange of information.

A communication node for relaying a signal between a source node and a destination node is disclosed. The communication node includes: a relay signal generation unit configured to generate a transmit signal by reducing, from a receive signal, an interference signal from another communication node and performing a process such that the transmit signal is not received as an interference signal by another communication node.

摘要:
A switch mode nucleic acid aptamer probe includes a probe main body, a fluorescence generating unit and a fluorescence quenching unit which are respectively connected to two ends of the probe main body. The probe main body includes a nucleic acid aptamer fragment with a function of specifically recognizing target tumor cell and a nucleic acid fragment linked to the nucleic acid aptamer fragment by a connection fragment with a length of 7˜15 nm so as to form a hairpin structure. The ability of competitive hybridization of the nucleic acid fragment with the nucleic acid aptamer fragment is weaker than that of the target tumor cell. The use of the probe of the invention can be at least one of specific detection of tumor living cell in buffer solution, effective detection of tumor living cell in serum, and real-time fluorescence imaging and intravital detection of tumor in living body.
