    Abstract

    This work presents an energy efficiency (EE) investigation of a beam generated by the combination of Recursive Least Square (RLS) algorithm and Kaiser side lobe cancellation technique in smart antenna system. The RLS-Kaiser combination is investigated using energy model which is a function of beam width, range and signal to noise plus interference ratio (SNIR). The investigation carried out on linear array geometry with element spacing 0.5 λ. The EE versus range and the EE versus beam width are examined. Finally, we have shown the advantage of using RLS-Kaiser combination during beam formation. And this combination helps for achieving both spectral efficiency (SE) and energy efficiency (EE) at the same time by avoiding interference because of side lobe and by saving the energy that would be wasted as a side lobe respectively. From the result, applying the side lobe attenuation factor in increasing order: 1.3226, 2.1166, 3.3953, and 3.9754 results in decreasing the amount of sidelobe level by 25dB, 30dB, 40dB, and 45dB) respectively with the expense of small increase in beam width. Therefore, even if the main beam width increased due to the saved side lobe energy, on the other hand, the energy efficiency of the generated beam getting improved as the attenuation factor changes from smaller to larger values.
