This paper presents the joint interference cancellation and equalization for space-time block coded (STBC) orthogonal frequency division multiplexing (STBC-OFDM) transmission over underlay cognitive radio network. In this work, pre- and post-FFT adaptive antenna array is employed at secondary user receiver to find optimum antenna weights that place

The aim of this research is to verify the potential of different floating macrophytes as a good phytoindicator for excess nutrients or bioindicator for nitrification and eutrophication in fresh water bodies. Domination of floaters in water bodies were investigated from 3 different states (Selangor, Pahang and Kelantan) in Malaysia. At each state, 1

The aim of this study is to determine the corrosion effect of palm oil methyl ester (POME) on aluminium alloy 5083 (AA5083). The static immersion test was carried out at 60°C for 68 days according to ASTM G-31-72. The corrosion analysis was done by using weight loss method and electrochemical test. The result from weight loss method shows the decr

The contribution of new products to corporate growth and survival has long been acknowledged. However, not much is known about the new product development (NPD) activities conducted by better performing companies compared to the lesser performing companies. It is the aim of this study to investigate the activities conducted by better performing com

Rubber (Hevea brasiliensis) leaf powder was modified by xanthation process and its potential in removing toxic Pb(II) ion from aqueous solutions was investigated in batch and column experiments. Pb(II) adsorption efficiency was found to be affected by several physicochemical parameters such as adsorbent dosage, shaking rate and temperature. The opt

Research from Islamic perspective should begin from the truth of the Quran and Sunnah (Acikgenj, 1996), the main source of Islamic knowledge. From the analysis of the main source of Islamic knowledge, theories are formulated and tested. We embark on this research to formulate techniques used by Prophet Muhammad to motivate students to perform bette

Customer satisfaction is one of the factors influencing customers loyalty to certain organization (Ranjbarian, Dabestani, Khajed & Noktehden, 2001). Therefore a study on the assessment and feedback from customers to ascertain that the products and services offered by the organization are well received needs to be carried out. This is important

This paper presents the two strategies of jointlyoptimized uncoordinated beamforming algorithms for cognitive radio networks. Here, we evaluate the performance of signal-tointerference-plus-noise ratio (SINR) and achievable sum rate of the system when both primary and secondary users transmit concurrently over the same spectrum. We present the opti

This article analyses the development of the administration of Syariah Courts in Malaysia from the pre-colonial to the post-independence periods. The status of Islam as the official religion during the Malacca Sultanate and the application of Islamic law throughout the administration during that period are agreed upon by most historians. The struct

We compared a newer serum specific IgE (SSIgE) test with skin prick testing (SPT) in the diagnosis of allergy in Malaysia. Ninety newly diagnosed allergic patients were enrolled for both tests. Using SPT as a clinical gold standard,the sensitivity, specificity, positive, and negative predictive values (PPV, NPV) were calculated for SSIgE for each o
