Cellular communication system continues to develop, starting from the first
generation (1G) until fifth generation (5G) that has emerged right now. The
enhancement of data traffic requires a better technology. 5G offers greater
throughput value than 4G. Just like 4G, multicarrier system is also used in 5G for
its physical layer. The current 5G standard uses orthogonal frequency division
multiplexing (OFDM) as its multicarrier system. Actually, there are other
mutlicarrier system that can be used for 5G. Generalized frequency division
multiplexing (GFDM) is one of those alternatives. Currently, there are not many
studies or reseach that discuss about the implementation of communication system
using GFDM.
In ths final project, a prototype of receiver system using GFDM is made with the
aim that the prototype receiver can receive information wirelessly at a frequency
of 3,5 GHz. To make the prototype, MATLAB is used to perform baseband signal
processing and SDR USRP E310 to receive RF signal. For GFDM parameters, the
number of subcarriers and subsymbols used are 4 and 16, respectively, and the type
of mapper used is 4-QAM. Testing is done by sending information in the form of
images and text from transmitter which will then be received by receiver. From the
test results, it is found that the receiver is able to receive information sent from the
transmitter, although there is still a mistake in the received information and the bit
error rate (BER) value is still quite high.
