Abstract: A wireless LAN apparatus based on multiple queues is provided to perform transmission scheduling according to channel conditions in consideration of the time varying property of a wireless channel and control a transmission rate adaptively, thereby improving the performance of the wireless LAN apparatus. A wireless LAN(Local Area Network) apparatus includes plural queues(310), a wireless channel estimator, a multiple queue scheduler(320), a channel access controller(330), a physical layer processor(340), and a queue group scheduler. Each of the plural queues stores at least one transmission frame and outputs at least one transmission frame sequentially. The multiple queue scheduler selects at least one of the plural queues based on estimated channel properties. The wireless channel estimator converts the transmission frame, to which channel access parameters are set, into a signal in a physical layer and transmits the converts signal through a wireless channel corresponding to the selected queue. The queue group scheduler is provided as many as plural queue groups grouped according to a predetermined standard. The queue group scheduler selects at least one of the transmission frames from a queue selected by each of the plural multiple queue schedulers and transmits the selected one to the channel access controller.

Abstract: An OCHM(Orthogonal Code Hopping Multiplexing) system employing an adaptive beam forming array antenna is provided to prevent transmission quality deterioration due to symbol collision and perforation by applying spatial filtering to an OCHM scheme. A transmitter includes a hopping pattern generator(140), an orthogonal code generator(146), a bandwidth spreading unit, and an adaptive beam forming array antenna. The hopping pattern generator generates orthogonal code hopping patterns corresponding to forward link communication channels to respective second communication stations. The orthogonal code generator generates orthogonal codes to be allocated to respective symbol intervals of the orthogonal code hopping patterns. The bandwidth spreading unit generates transmission signals by spreading transmission symbols using the generated orthogonal codes. The adaptive beam forming array antenna generates weighted vectors corresponding to the forward link communication channels based on angle-of-arrival information of the respective second communication stations, applies the weighted vectors to the transmission signals, and transmits the applied result to the respective second communication stations through plural beam forming antennas.
