The 5G N77 band resonating at 3.5 GHz is addressed by a compact (20 mm x 12 mm x 0.8 mm) hook-shaped microstrip antenna which is presented in this paper. The suggested planar patch is printed on the inexpensive FR-4 substrate of 0.8 mm thickness. The proposed hookshaped antenna is fabricated and its network parameters are measured using a Network analyzer. The fabricated antenna results closely match...
OFDM is recently widely using many wireless and wire line communication systems. Addition of impulse noise limits communication performance in certain OFDM systems. Impulse noise immunity comes from extended symbol duration, since the impulse noise is usually of very short duration compared to symbol duration in parallel transmission. Impulse noise affects all the sub carriers in a symbol due to the...
Orthogonal Frequency Division Multiplexing (OFDM) is a popular and widely accepted modulation technique in the area of wireless communication. Multi-user version of the OFDM system is called Orthogonal Frequency Division Multiple Access (OFDMA). Although OFDM and OFDMA have many benefits contributing to its popularity, a well-known drawback of multicarrier transmission is its inherited large peak-to-average...
Orthogonal frequency Division Multiplexing (OFDM) is an attractive technology in Wireless Communication. High Peak-to-Average Power Ratio (PAPR) is one of the challenging issues in OFDM systems. High PAPR force the High Power Amplifier (HPA) to operate in its linear region with wide dynamic range, where the power efficiency is very poor. The poor power efficiency makes the reduction of PAPR more important...
