Currently, Sarawak, Sabah and Brunei are still using the third generation (3G) mobile communication technology. Mobile users demand faster download at good quality of services. Fourth generation (4G) or Long-Term Evolution (LTE) is a promising candidate. LTE physical downlink layer with MIMO-OFDM receiver can achieve multiplexing gain and improve symbols decoding. Adaptive modulation enable switching modulation type according to acceptable bit error rate or signal-to-noise ratio.
