Web• Example: 6-bit input wi th 8-tap FIR might have 10-bit coefficient word lengths. • Example: 12-bit input with 128-tap FIR might have 18-bit coefficient word lengths for 72 dB output SNR. • Requires multiplies in filter and adaptation algorithm (unless an LMS variant used or slow adaptation rate) Study of FFE location has been gaining more attention. Work of proposes a long TX FIR that results in a simpler receiver and more power efficient link. As shown in Figure 1(a), the authors of suggest that moving the receiver FFE to the transmitter side would decrease the RX FFE power due to digital multiplications. … See more The nonidealities considered in this analysis are ISI, modeled by the pulse responses, and an independent identically distributed (i.i.d.) … See more Another motivation for putting the FFE on the RX side is the equalizer adaptation capability. When adapting FFE on the TX side, a back channel … See more Figure 10 shows the modified block diagram of the system of interest. A DAC is added after the TX FFE and an ADC is placed before the RX … See more In this section, we include more realistic system building blocks, such as DACs and ADCs, to understand their effects and limits in the context of FFE equalization and system … See more church house inn churchstow kingsbridge
