what is the difference between estimation, equlization and detection in communication systems? specially in ofdm technique ?
 

Coherent and noncoherent detection
◮ absolute modulation −→ channel equalisation, coherent detection
◮ differential modulation −→ noncoherent detection

2. Estimation principles
◮ least squares
◮ MMSE

3. Data estimation
◮ least-squares design −→ zero-forcing equaliser
◮ MMSE design −→ MMSE equaliser
◮ equalisation in OFDM: one multiplication per subcarrier
◮ GDFE, THP, TEQ
