Abstract

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, Research on the PCFICH in eNodeB, a simple implementation approach is proposed in the TMS320C64xDSP, The program has been applied to the development of LTE-TDD wireless integrated test instrument. The running results verify that the program is feasible and effective.
