Adaptive Beam Formation in Smart Antenna â€“ A New Combined Method Using Tchebyscheff Distribution and Constrained Stability Least Mean Square Algorithm
Keywords:Smart antenna, CSLMS, TDCSLMS, side lobe reduction
Adaptive beam-formation in smart antenna using constraint stability least mean square (CSLMS) algorithm along with Tchebyscheff distribution (TDCSLMS) is reported in this paper. Different values of pre-defined side lobe levels are considered for Tchebyscheff distribution. The results of adaptive beam formation are compared with respect to desired beam direction, null direction, beamwidth and maximum side lobe level (SLL). Using TDCSLMS, lower side lobe levels are achieved compared to CSLMS for various angles of desired user and undesired interferer.
