Integrated circuit modem with a memory storage device for generating a modulated carrier signal

摘要: An apparatus capable of transmitting digital data at high rates over a communication link is disclosed. A carrier signal modulated by serial groups signals to be transmitted during plurality successively appearing modulation periods. The data-modulated represented unique group stored in memory. memory upon command, reads out predetermined sequence with each representing the shape which appears as though it has been passed through narrow band limited linear phase network. stores number such sequences signals. four one preferred embodiment this invention. In that embodiment, occupies spectrum frame extends time successive Timing transmitter insures starting offset period relative start preceding frame. summing circuit connected between storage device and an input adds they are read from order. operation generates composite for application link.
