Abstract

As mobile communication technologies have evolved rapidly during the last few years, wireless communication standards such as WiMax and LTE are developed with the need of new services on mobile devices. In this thesis, the design and implementation of the encoder and decoder of Physical Hybrid ARQ Indicator Channel(PHICH)of LTE are presented. PHICH carries Acknowledgements(ACKs) and Negative Acknowledgements(NACKs)from the base station (eNodeB) to the mobile devices (UE). The encoder is designed to encode the ACK/NACK sent from the base station to the UE while the decoder is designed to decode the encoded data and provide control information for the UE. The encoder and decoder are implemented in MATLAB.
