Fractionally spaced equalizers with adaptive sampling
Miwa Sakai, Kiyoharu Aizawa, M. Hatori · 2002
A new structure of fractionally spaced equalizer (FSE) is described. A conventional FSE has taps spaced equally T/M, where T is the symbol spacing and M is an integer. Although there are many advantages of FSE in digital data transmission, the computational requirements increase with factor M. We describe a non-equally spaced FSE (NFSE) with less computational requirements. A novel tap control algorithm for NFSE under some restrictions is also presented.>
