| Summary: | Synchronization in Orthogonal Time Frequency Space (OTFS) communication
systems faces specific challenges, particularly in high-mobility wireless
environments. In recent years, OTFS has gained significant attention from
researchers in the field of wireless communication, as it is expected to be a more
robust modulation technique for overcoming challenges in wireless environments.
Carrier Frequency Offset (CFO) is one of the primary issues that can disrupt OTFS
kinerjance. The main objective of this research is to develop an effective
synchronization mechanism for precise CFO estimation to ensure robust signal
reception at the receiver. The proposed synchronization technique employs the
preamble method, utilizing two types of preambles: the Zadoff-Chu (ZC) sequence
and the IEEE 802.11a standard. Testing was conducted by transmitting data in the
form of images and text. The kinerjance of the synchronization technique was
evaluated using Mean Square Error (MSE). The test results indicate that the ZC
sequence preamble method provides better outcomes compared to other methods,
and longer preamble lengths also positively impact the performance of CFO
synchronization techniques. |
