Broadband communication is one of the high demanding requirements of today’s world, where LTE-Advanced does not only focuses on the further enhancement of their data rates but also on reducing the total cost of the system with greatest throughput and performance. In achieving the high throughput LTE-Advanced has to suffer a major problem of power degradation and its effect on the continual disturbance in offset of carrier frequency(CFO). These problems of power(PAPR) and Carrier offset can be minimized if the control over higher carrier aggregation be achieved, which will increase the LTE-Advance system performance significantly.

This paper investigated the effect of power ratio (peak to average) and offset of carrier frequency in LTE-Advance Uplink system’s performance and proposed a novel technique using the partial transmit sequence and pilot symbols by applying proposed phase sequence generation method to reduce the ratio of peak power to the average power without having the effect on the frequency offset of carrier. The implemented technique maintained the low PAPR by 4db (76%) with perfect orthogonality among carriers without effecting the carrier frequency offset and reducing the complexity of the system.
