The constant evolution in communications has lead to the development of new technologies such as LTE and SDR systems. This dissertation presents the development of a LTE-based SDR system for the ORCIP testbed. A detailed study of LTE technologies and standards is firstly presented, in order to ensure a complete understanding of the topic. Subsequently, using MATLAB, a configurable LTE transmitter and receiver are designed while taking into the corresponding standarts. The functionally of the transmitter and receiver include generating and decoding LTE waveforms with multiple parameter choices such as bandwidth, modulation order, number of subframes, among others. With these modules a carrier aggregation implementation is also performed. To complete the SDR system, an oscilloscope and an arbitrary waveform generator were connected to verify the implemented LTE modules. The generated LTE signals are loaded to the AWG and the waveforms captured by the oscilloscope are processed with the developed LTE receiver. Test based on EVM measurements are performed for both single carrier and carrier aggregation scenarios. The obtained results confirms a good performance for both single carrier and carrier aggregation, which proves that the system implementation can be applied to testbed systems; e.g. ORCIP testbed.
