Objective: Designing energy efficient mobile communication system is the main challenge for the LTE researchers due to increasing of users and their demands in accessing broadband services on mobile phones. High data rate, reduced Bit Error Rate (BER) and low Peak to Average Power Ratio (PAPR) are the requirement of the current telecommunication technology in both uplink and downlink. In this paper, various modulations techniques (QPSK, BPSK and QAM) and pre-coding schemes (DPC, THP, and RS) are proposed to analyze the uplink characteristics. Methods/Analysis: This paper investigates Single Carrier Frequency Division Multiple Access (SC-FDMA) and performs its link level models with Tomlinson-Harashima Precoder (THP) and Reed Solomon coding (RS) in separate and integrative manner which is proposed. Findings: In order to prove the hypothetical results, various simulations performed for BER of SC-FDMA system. Results proved that the integration of THP and RS coder in the SC-FDMA transmission, improves the system performance in case of BER. The proposed techniques can be implemented in GPRS, UMTS, GSM, EDGE, HSPA and LTE.
