This paper will describe how to implement the LTE uplink transceiver specifications on software defined radio platform. LTE (Long Term Evolution) is important for fourth generation of mobile communication technologies. On the uplink transmission system, the LTE system uses SC-FDMA (Single-Carrier Frequency Division Multiple Access) technology. The SC-FDMA structure is like as OFDMA (Orthogonal Frequency Division Multiple Access). SC-FDMA pre-coded the information-bearing symbols by DFT (Discrete Fourier Transform). This pre-coding operation can reduce PAPR power.It can benefit power efficiency which used in mobile terminal and it can extend the usage time of the battery. It also can reduce manufacturing cost.
In this thesis, we conduct design and implementation of LTE uplink transceiver with FPGA (Field-programmable Gate Array) and RF component(AD9361). The transceiver can be realized with the Software Defined Radio platform. The transmitter includes parallel-to-serial module, constellation mapper, DFT, Invers FFT, cyclic prefix inserter and pilot inserter. The receiver includes signal synchronizer, FFT, channel estimator, channel equalizer, Invers DFT etc. |
