An ECU of a reception side restores the original baseband data by performing a second conversion of the received transmission data. The second conversion is the reverse of the first conversion. The ECU of the transmission side transmits the transmission data that includes a training pattern, which indicates a bit period of the transmission data, in addition to the after-conversion baseband data. The ECU of the reception side specifies the bit period of the transmission data based on the training pattern in the received transmission data.

Abstract: A channel equalization scheme is provided. A linear equalizer using a continuous-time linear equalization and a decision feedback equalizer using a discrete-time decision feedback equalization are integrated together from a hybrid receiver equalizer. The continuous-time linear equalization scheme and the discrete-time decision feedback equalization scheme are blended using a joint adaptation algorithm to form an equalization scheme for inter-symbol interference cancellation in the hybrid receiver equalizer. The hybrid receiver equalizer controls crosstalk while maintaining signal bandwidth and linearity of a signal by the high-order high frequency roll-off of the linear equalizer used. Using this configuration, the hybrid receiver equalizer eliminates the need for adaptive bandwidth controller used in conventional low-pass receiver equalization schemes. The hybrid receiver equalizer can be used in receivers for dual-speed simultaneous transmission on the same physical link.
