ABSTRACT:
In a telephone local loop transmission arrangement, data is communicated from the customer premises to the central office utilizing a multidimensional, passband signal illustratively at 480 kb/s. Specifically, the transmitted signal is encoded in a trellis code and the received signal is processed by a circuitry that implements decision feedback equalization in combination with trellis decoding.
