  1. Array Antennas for Packet Transmission Networks Antonio Pascual Iserte, Nada Ahmed Awad, Ana I. Pérez-Neira DEPT. OF SIGNAL THEORY AND COMMUNICATIONS POLYTECHNIC UNIVERSITY OF CATALONIA (UPC) Communications Signal Processing Group, Barcelona, SPAIN TELECOMMUNICATIONS TECHNOLOGICAL CENTER OF CATALONIA (CTTC), Barcelona, SPAIN {nahmed,tonip,anuska}@gps.tsc.upc.es Workshop on Broadband Wireless Ad-Hoc Networks and Services, 12th-13th September 2002, ETSI,Sophia Antipolis,France

  2. Ad-hoc networks operate in the unlicensed 2.4GHz ISM band. Different types of Interference sources. Use of spatial diversity schemes to combat interference in a time variant interference scenario. receiver architecture enhanced with the Generalized Sidelobe Canceller (GSLC). Simulations

  3. Generalized SideLobe Canceller Signal Model: Array design -“quiescent”: -blocking matrix: -adaptive beamvector: (NLMS)

  4. SNIR behavior for (non-)adaptive algorithms (GSLC).

  5. BER evaluation for (non-)adaptive algorithms (GSLC). PARAMETERS -Angular spread: 15º -IEEE 802.11b interference: mean SIR = -10 dB
