Abstract(in English) | This paper proposes an adaptive multipath control technique using window size controlled wide null creation technique (WNCT) for the adaptive array antenna (AAA) systems in rich scattering channel conditioned broadband wireless communication systems. In the proposed scheme, deep null creation technique (DNCT) and WNCT are employed to create antenna directivity for transmission so that unwanted radiation to the adjacent sectors or cells can be suppressed. Moreover, to efficiently utilize small number of degree of freedom of the AAA under rich scattering channel conditions, we will introduce an window size control technique in the WNCT by which we can create wider null to a direction of interference cluster with strong and large angle spread. Computer simulation confirms that WNCT with the proposed window controlling technique can achieve higher carrier to interference plus noise power ratio (CINR) than the original WNCT in the uplink. |
