Good Agreement

A new dual-broadband printed dipole antenna for base station applications is proposed in this communication. This antenna has three different dipoles with the same feed point and an extra parasitic strip. The two arms of the three dipoles are printed on opposite sides of the substrate and symmetrical on the centerline, but the parasitic strip at the end of the dipole is just put on one side. Besides, a U-shaped reflector is designed at the bottom of the antenna to realize good radiation characteristics in the working frequency. The simulated and measured results show good agreement. The two studied bands are both broadened which, respectively, achieve 36.7% (690–1000MHz) and 47.3% (1710–2770MHz) for the lower and higher bands so as to satisfy the 2G/3G/4G wireless communication, and the corresponding gains of 4-5dBi and 5-6dBi are also obtained.

Single-carrier FDMA (SC-FDMA) is becoming more and more popular in multiuser communication because of its lower PAPR value. Apart from this, many other hybrid access techniques have also been explored in the literature for application to 4G wireless mobile communication. Still there is a need to explore newer techniques which could further reduce the PAPR value without any degradation in system BER. Keeping this in view, a modified hybrid technique SC-FDMA-DSCDMA has been proposed in this paper and it is found to provide significantly lower PAPR than SC-FDMA system with no degradation in BER performance. This paper extensively compares the BER and PAPR performance of various other multicarrier techniques for 4G wireless communications such as OFDMA, MC-DS-CDMA, and SC-FDMA with proposed SC-FDMA-DSCDMA scheme. Simulation results show that SC-FDMA-DSCDMA technique performs better than any other OFDM-CDMA based system for wireless communication.
