Abstract:
The present invention relates to a wireless communication apparatus operated in a dual band triple mode supporting a machine type communication (MTC) service operable in a TV white space area and a cellular frequency band, and an operation method thereof. To this end, the TV white space area and the cellular frequency band representing a dual band are supposed to be an operation frequency band considered in the present invention, and a PAN coordinator and an LTE-advanced base station TV band device (TVBD) essential for a triple mode operation are considered as elements. In addition, an MTC server concept is introduced for providing an individual MTC wireless device user with a smooth service and management. For accurate information provision for an MTC server, interoperability consideration between wireless devices, and an optimal service operation, the present invention has an interactive structure for an individual database (Hereinafter, DB) including a detailed service process structure and information on a service environment considered for each individual triple mode operation process.

Abstract:
PURPOSE: A multi coexistence communication system based on an interference-aware environment and a driving method thereof are provided to recognize a situation about interference using an interference temperature limit value, thereby transmitting the signal after removing the interference value from a transmission signal. CONSTITUTION: A sub base station(200) generates a sub transmission signal by itself. The sub base station inputs a frequency bandwidth and an interference temperature limiting value. The sub base station determines frequency usage capacity according to the inputted interference temperature limiting value. The sub base station assigns the frequency bandwidth of a sub communication terminal(400) in the determined capacity.
Abstract:
A platform and a method for reconfiguring a reconfigurable base station are provided to offer a user high quality service as well as to enhance efficiency of frequency resources by changing frequencies or services selectively according to an environment, a user request or QoS(Quality of Service). A platform for reconfiguring a reconfigurable base station includes a CR(Cognitive Radio) function unit(100) and an SDR(Software Defined Radio) platform(200). The CR function unit actively recognizes a situation like a channel feature caused by different frequencies, time assignment distribution or unique environment characteristics and assigns available wireless resources to a user based on the recognized information. The SDR platform reconfigures flexibly a transmitting or receiving system like a base station or a terminal via a software based on transmitting or receiving algorithm information like information on frequencies, bandwidth, a multiplexing scheme, a modulating/demodulating scheme, channel coding, transmission power and others.
Abstract:
A method for optimizing cognitive radio communication system variables and a computer-readable recording medium storing a program therefor are provided to increase a convergence speed by allocating an arbitrary solution within a target range as a system variable of radio communication and reducing radio configuration genes of a chromosome used for a gene algorithm. System variables required to be optimized by the user of radio communication are set as knobs or meters(S1). A target that can be set in the system with respect to the set knobs or meters is set(S2). A solution within the bounds of the target is extracted among solutions of the system variables(S3). System variables are set according to the solution(S4).
