In this paper, we consider diffusive molecular communication (MC) systems\naffected by signal-dependent diffusive noise, inter-symbol interference, and\nexternal noise. We design linear and nonlinear fractionally-spaced equalization\nschemes and a detection scheme which combines decision feedback and sequence\ndetection (DFSD). In contrast to the symbol-rate equalization schemes in the MC\nliterature, the proposed equalization and detection schemes exploit multiple\nsamples of the received signal per symbol interval to achieve lower bit error\nrates (BERs) than existing schemes. The proposed DFSD scheme achieves a BER\nwhich is very close to that achieved by maximum likelihood sequence detection,\nbut with lower computational complexity.\n
