Multiple encoded carrier data link
First Claim
1. A data link having forward error correction for substantially error-free transmission of input data from one source to a target point, said data link comprising:
- a transmit data processor means for receiving input data from said one source, for encoding said input data into a plurality of transmit data streams, and for providing one of said plurality of transmit data streams at each of a plurality of outputs said transmit data processor means comprising;
transmit radio means having an input coupled to a different processor output for receiving a corresponding transmit data stream, for generating a carrier signal having a frequency within a band of frequencies wherein each carrier signal varies in frequency within said band at random, independent of other carrier signals, and for modulating said carrier signal with said transmit data stream;
transmit antenna means for receiving and radiating said modulated carrier signal;
receive antenna means for collecting said transmission signals and for providing collected signals;
a plurality of receive means, each for receiving said collected signals and for extracting receive data streams from said collected signals, each of said receive data streams corresponding to one of said transmit data streams; and
receive data processor means having a plurality of inputs, each of said inputs coupled to a respective said receive means, said inputs for receiving each of said receive data streams, said received data processor means for decoding and recombining said receive data streams so as to regenerate said original input data as output data to said target point.

Abstract
A modular data link having a transmit processor for receiving input data and for providing different portions of the input data at each of a plurality of outputs. A plurality of transmit channels each receive an input data portion and transmit a signal corresponding to the received input data portion. An antenna collects the transmitted signals and provides an output thereof. A plurality of received channels each receive the collected signals from the antenna and extract a different input data portion from the collected signals. A receive processor having a plurality of input each coupled to a respective receive channels receives the extracted different input data portions so as to recombine the different input data portions in regenerating said original input data as output data.

7. A communications system having an up-link and down-link, each being a data link having forward error correction for substantially error-free and jam-resistant transmission of data from one first point to a second point, said communications system comprising:
-
a transmit data processor means for receiving input data from said first point, for encoding said input data into a plurality of transmit data streams, and for providing one of said transmit data streams at each of a plurality of outputs; a plurality of transmit radio means, each for receiving one of said transmit data streams for converting said transmit data streams to converted transmit data streams having a form suitable for transmission, each said transmit radio means being coupled to a different transmit data processor output for receiving a corresponding transmit data stream, for generating a carrier signal which varies in frequency within a band of frequencies at random, independent of carrier signals of other transmit radio means, and for modulating said carrier signal with said transmit data stream, providing a modulated carrier signal; transmit antenna means for receiving and radiating transmission signals corresponding to said converted transmit data streams; receive antenna means for collecting said transmission signals and for providing collected signals; a plurality of receive means each for receiving said collected signals and for extracting a receive data stream from said collected signals corresponding to one of said transmit data streams; and receive data processor means having a plurality of inputs each coupled to a respective receive means for receiving each of said receive data streams, said receive data processor means for recombining said receive data streams so as to regenerate said original input data as output data; wherein said up-link is for transmitting data in a first direction from said first point to said second point, and said down-link is for transmitting data in a second direction opposite to said first direction. - View Dependent Claims (8, 9, 10, 11, 12, 13)
