1. A bandwidth constrained equalized transport (BCET) communication system, comprising:
a transmitter that transmits a signal comprising symbols, comprising:
an error control code encoder;
a pulse-shaping filter; and
a first interleaver;
a communication channel that transports the signal; and
a receiver that receives the signal, the receiver comprising:
a receiving filter;
an information-retrieving equalizer;
a deinterleaver with an error control code decoder;
a second interleaver; and
a neural network (NN) processing block that processes the received signal, wherein:
the error control code encoder appends redundant information onto the signal;
the pulse-shaping filter intentionally introduces memory into the signal in the form of inter-symbol interference;
the first interleaver changes a temporal order of the symbols in the signal;
the information-retrieving equalizer, the second interleaver, and the deinterleaver with the error control code decoder are joined in an iterative turbo equalization loop;
the NN processing block is coupled to an output of the turbo equalization loop, and the NN processing block processes the signal after one or more iterations of the turbo equalization loop;
the BCET communication system is bandwidth constrained; and
the signal comprises an information rate that is higher than that of a communication system without intentional introduction of the memory at the transmitter.
