Patent ID: 8842513

Claim:
A communication system comprising: a System-on-Chip (SoC) comprising a first intellectual property (IP) and a second IP, the first intellectual property (IP) configured to modulate a data and the second IP configured to demodulate the modulated data received from the first IP; and a plurality of transmitting nodes including a first transmitting node of the first IP, a plurality of receiving nodes, including a second transmitting node of the second IP, and a communication structure providing a communication link between the transmitting nodes and the receiving nodes, wherein the data consists of ‘1’ and ‘0’ before being spread by an orthogonal code, wherein each transmitting node is configured to spread data by a corresponding one of a plurality of orthogonal codes and to provide the spread data to the communication link, wherein each receiving node is configured to receive spread data from a transmitting node via the communication link and despread the spread data using a corresponding one of the plurality of orthogonal codes, wherein the plurality of transmitting nodes includes a first transmitting node and the plurality of receiving nodes includes a first receiving node, and wherein the first receiving node is configured to obtain data of the first transmitting node when an orthogonal code used by the first receiving node to despread the data is the same as the orthogonal code used by the first transmitting node to spread the data.
