Patent ID: 11863366
Assignee: CABLE TELEVISION LABORATORIES, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 19:
20. A digital transmission system, comprising:
a transmitter configured to transmit an input series of complex symbols;
a duobinary encoder in communication with the transmitter, and configured to receive the input series of complex symbols and output a partial response signaling (PRS) signal;
a converter in communication with the duobinary encoder, and configured to (i) convert the PRS signal output into the time domain, and (ii) construct a duobinary OFDM signal for transmission by splitting a subcarrier of the input series of complex symbols to appear over two adjacent frequency domain subcarriers; and
a receiver for receiving the time domain-converted PRS signal from the transmitter over a signal path.
