Equalization process includes : 

The correct answer is maximum likelihood sequence estimation and equalization with filters.

Key Points

• The equalization process involves two major techniques: maximum likelihood sequence estimation (MLSE) and equalization with filters.
• MLSE is a method used to estimate the transmitted sequence of symbols by finding the most likely sequence that could have been transmitted given the received signal.
• Equalization with filters is used to combat the inter-symbol interference (ISI) that occurs during signal transmission over a communication channel.
• Combining these techniques helps to significantly improve the accuracy and quality of the received signal.
• By using filters, the system can adapt to varying channel conditions and mitigate the effects of noise and interference.

Additional Information

• MLSE can be computationally intensive, but it provides optimal performance in terms of minimizing the error rate.
• Common filtering techniques used in equalization include linear equalization, decision feedback equalization (DFE), and adaptive equalization.
• Equalizers can be designed to work in the time domain or the frequency domain, depending on the application and system requirements.
• Adaptive equalizers adjust their parameters in real-time to cope with changing channel conditions, ensuring robust performance.
