Abstract

Long Term Evolution (LTE) of the Universal Mobile Telecommunication System (UMTS) is a 3^rd Generation Partnership Project (3GPP). It is a 3.9 Generation (3.9G) Radio Access Standard, but it is advertised as 4^th Generation (4G) by Mobile Carriers. The control information is transmitted to the user equipment (UE) present in the cell through Physical Downlink Control Channel (PDCCH). This paper deals with the implementation of PDCCH Transmitter and Receiver by employing QPSK and 16QAM as modulation schemes. 16QAM modulation improves performance and reduces the power consumption when compared to QPSK. The result analysis displays improvement in frequency and reduction of power consumption. The design is simulated in Modelsim 6.3g and implemented in CMOS 180nm technology using Cadence RTL Compiler.
