The Microstrip patch antenna has a dielectric substrate with a radiating patch and the feed lines are etched on one side and a ground plane on the other side. The shape of the patch is not constrained (could be square, rectangular, circular, triangular or elliptical) and it is generally made of conducting material such as copper or gold. These antennas are mostly used at microwave frequencies, the fringing fields between the patch edge and the ground plane cause the microstrip patch antennas to radiate

We are using orthogonal frequency division multiplexing (OFDM) modulation technique for Energy harvesting and information transfer. OFDM is most efficient and noise resistant scheme of modulation in wireless communication technology. Orthogonal frequency-division multiplexing (OFDM) is a method of digital modulation in which a signal is split into several narrowband channels at

IEEE 802.16 standard and it’s mainly roots in CDMA. Frequency of operation: LTE operates at lower frequency as compared to wimax. Higher the frequency of operation, higher the attenuation. Both wimax and LTE uses OFDM (Orthogonal Frequency Division Multiplexing). OFDM uses orthogonal frequencies as carrier frequencies so that there will be no interference between the signals i.e. it uses the principle of orthogonality. This in turn improves the spectral efficiency. Multiple Access: Both LTE and wimax

OFDM is a great technique to handle impairments of wireless communication channels such as multipath propagation. Hence, OFDM is a practical candidate for future 4G wireless communications techniques [1]-[4]. On the other hand, one of the major drawbacks of the OFDM communication system is the drift in reference carrier. The offset present in received carrier will lose orthogonality among the carriers. Hence, the CFO causes a reduction of desired signal amplitude in the output decision variable and

Abstract- In this paper, ordered successive interference cancellation (OSIC) is adopted with minimum mean square error (MMSE) detection to enhance the multiple-input multiple-output (MIMO) system performance. The optimum detection technique increases the system complexity with improved error rate performance. Therefore, MMSE-OSIC detection is used which gives reduced error rate compared to traditional MMSE with a considerable level of complexity. The system performance is analyzed in a composite
