Enhancement of Oversampling Scheme to Achieve Diversity Gain in Wireless Communication by Feedback Equalization Algorithm

With the increase in popularity for wireless communication systems, the demand for larger data rates has also increased exponentially. One way to increase the data rate is to transmit more data in a given channel. Oversampling is a scheme used to achieve this goal by sampling the signal at higher frequencies. This increases the number of symbols transmitted, which translates to an increase in data rate. However, this technique often suffers from the issue of inter-symbol interference (ISI). To address this issue, techniques such as interpolation and frequency domain methods can be employed. In addition to increasing the data rate, oversampling can also offer diversity gains. By oversampling a signal, uncorrelated versions of the same signal are obtained. This opens up opportunities to employ techniques such as space-time coding and frequency hopping to achieve diversity gain. Space-time coding (STC) is a way of transmitting data on multiple antennas within a single time and frequency slot. This allows for more independent transmission paths and improves the quality of the received signal. Frequency hopping (FH) involves switching the frequency of transmission repeatedly during transmission. This increases transmission rates, but also provides diversity gains. Recent studies have shown the enhancement of oversampling schemes, such as space-time coding and frequency hopping, to further improve the data rate and diversity gain of wireless communication systems. By using both of these techniques, it is possible to achieve a higher data rate while also having the flexibility to adapt to changing channel conditions. This allows for a more reliable system that is capable of providing greater data rates, while also enabling the system to adjust to varying channel conditions. Furthermore, utilizing these techniques in conjunction with compression and other signal processing methods helps to reduce the impact of ISI, thus further enhancing the system's performance.
