PCFICH channel design for LTE using FPGA

Realization of transmitter and Receiver architecture for LTE is the major research work being carried out by implementation experts. There are four Control channels available in LTE for both uplink and downlink. The uplink control channel is PUCCH. The downlink control channels are PDCCH, PCFICH and PHICH. The Physical Control Format Indicator Channel(PCFICH) is one among the downlink physical control channel and it carries the number of OFDM symbols used by the PDCCH channel, denoted as Control Format Indicator(CFI). These control channels play a key role in the correct decoding of the payload information. The CFI is the first information received by the User and so is important for the system performance. In this paper, the realization of architecture for the PCFICH are done using FPGA, where the main aim is to estimate the CFI correctly in the receiver side. The simulations are done using Modelsim and are implemented in Xilinx Spartan 3E kit.
