    IPC: H04B7/26

    Abstract: CAPACITY HAS BECOME OF PRIMARY IMPORTANCE IN WIMAX MESH NETWORKS (WMN) DUE TO THE EVER INCREASING DEMAND FOR MULTIMEDIA SERVICES AND THE POSSIBILITY OF PROVIDING HIGH SPEED WIRELESS INTERNET. THE MAJOR FACTOR LIMITING CAPACITY IN SUCH SYSTEMS IS INTERFERENCE ORIGINATING FROM ADJACENT NODES, NAMELY CO-CHANNEL INTERFERENCE. THE PRESENT INVENTION IS GENERALLY AN ANALYSIS OF CO-CHANNEL INTERFERENCE FOR A SPECTRALLY EFFICIENT WMN CONFIGURATION. A NEW CHANNEL ALLOCATION ALGORITHM IS PROPOSED BY USING SMART ANTENNA SYSTEM TO ELIMINATE THE CO-CHANNEL INTERFERENCE. THIS ALGORITHM CONSIDERS THE NUMBER OF SUBCHANNELS IN THE OFDM SPECTRUM IN ORDER TO INCREASE THE SYSTEM CAPACITY. THE NEW ALGORITHM IS DESIGNED TO AVOID THE SAME SUBCHANNEL OF OFDM SPECTRUM TO BE ALLOCATED IN ADJACENT NODES. THE SYSTEM CAPACITY CAN BE INCREASED WHEN THE CO-CHANNEL INTERFERENCE IS REDUCED.

    Abstract: THE PRESENT INVENTION DISCLOSES A METHOD AND SYSTEM OF COOPERATIVE DATA RELAY IN A WIRELESS MESH NETWORK. THE SYSTEM COMPRISES AT LEAST ONE MULTI-HOP RELAY BASE STATION (MR-BS) (100) AND A PLURALITY OF RELAY STATION (RS) (200) WHICH ARE CONFIGURED TO SUPPORT MESH CONNECTIONS. THE METHOD IN ACCORDANCE WITH THE PREFERRED EMBODIMENTS OF THE PRESENT INVENTION PROVIDES CAPABILITIES TO ENABLE OPTIMAL DATA TRANSMISSION BY WAY OF COOPERATIVE RELAY BETWEEN THE RELAY STATIONS (RS) (200). DATA TRANSMISSION IS INITIATED UPON ESTABLISHED THE OPTIMIZED MULTIPLE PATHS WITH RESPECT TO THE RELAY STATIONS (RS) (200). THE DETERMINATION OF THE OPTIMIZED MULTIPLE PATHS IS BASED THE DETAILS OF RELAYS STATIONS (RS) (200) PROVIDED TO THE REFERENCE TABLE AND CENTRALIZED SCHEDULING AT THE MULTI-HOP RELAY STATION (MR-BS) (100). THE REFERENCE TABLE AND CENTRALIZED SCHEDULING INCLUDE, BUT NOT LIMITING TO, ALL DETAILS AND STATUS PERTAINING TO THE PLURALITY OF RELAY STATIONS (RS) (200) WITHIN THE NETWORK, NETWORK CONDITION AND TRAFFIC TYPE.

    Abstract: THIS INVENTION RELATES TO A METHOD TO DYNAMICALLY ENHANCED THE PERFORMANCE OF DATA TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM AND MORE PARTICULARLY TO THE MULTIPLE INPUT MULTIPLE OUTPUT (MIMO) OF THE COMMUNICATION SYSTEM. THE METHOD PROPOSED BY THE PRESENT INVENTION INCLUDES CREATING FLEXIBLE PARAMETERS TO THE MULTI-ELEMENTS ANTENNA ARRAY AND UTILIZING OF SPACE TIME CODING (STC) AND SPATIAL MULTIPLEXING (SM) IN THE TRANSMISSION CRITERION AT THE BASE STATION (BS) (1). THE FLEXIBLE PARAMETERS ARE THE NUMBERS OF ANTENNA ELEMENTS N AND DISTANCE BETWEEN ELEMENTS D. THESE TRANSMISSION CRITERION AND MULTI-ELEMENTS ANTENNA ARRAY CHANGING ACCORDING TO FEEDBACK FROM THE RELAY STATIONS (RS) (2) AND THE RELAY STATIONS (RS) (2) ARE RECEIVING DATA FROM THE SUBSCRIBER STATIONS (SS) (3). FROM THE FEEDBACK FROM A PARTICULAR RELAY STATION (RS) (2), THE TRANSMISSION CRITERION SHALL DETERMINED EITHER TO USE SPACE TIME CODING (STC) OR SPATIAL MULTIPLEXING (SM) OR BOTH AND N AND D CHANGES ACCORDINGLY TO IMPROVE SIGNAL-TO-NOISE RATIO (SNR), BIT ERROR RATE (BER), DATA RATE, RELIABILITY ETC.

    Abstract: THE PRESENT INVENTION RELATES TO A COOPERATIVE COMMUNICATION AMONG A PLURALITY OF BASE STATIONS (BSS) 10 AND 12 FOR SENDING DATA PACKETS TO SUBSCRIBER SERVER (SS) 30 THROUGH A PLURALITY OF RELAY STATIONS (RSS) 20, 22, 24, AND 26. THE PRESENT INVENTION RELATES TO A METHOD OF MAKING THE PLURALITY OF BASE STATIONS COOPERATE WITH EACH OTHER BY EXCHANGING INFORMATION ABOUT THE CURRENT UTILIZED RELAY STATIONS. THE SERVING BASE STATION UPDATES THE NEIGHBORING BASE STATIONS WITH THIS INFORMATION, THUS THIS COOPERATION IS ABLE TO MAXIMIZE THE USAGE OF THE FREE RELAY STATIONS. THE PRESENT INVENTION RELATES TO A METHOD TO REALLOCATE THE SOURCES (RELAY STATIONS) IN A MORE EFFICIENT MANNER, MEANS SUBSCRIBER STATION WITH HIGHER NEED IS BE ABLE TO UTILIZE THE FREE RELAY STATIONS TO FORWARD ITS SIGNAL COMING FROM THE SERVING BASE STATION.
