Abstract:
1. A communication network using code division multiplexing technology, comprising: plural communication terminal interfaces, each of which has a first decoding circuit for decoding received data using a defusing code of a first code length and decoding received control signal using a defusing code of a second code length that is different from said first code length, and a first encoding circuit for encoding transmission data using a spreading code of said first code length and encoding transmission control signal using a spreading code of said second code length, a server which has a second decoding circuit for decoding received control signal using spreading codes of said second code length, and a second encoding circuit for encoding transmission control signal using spreading codes of said second code length, a communication circuit which connects said communication terminal interfaces and said server each other, wherein the spreading codes of said second code length are the values acquired by carrying out the multiplication of the same constant number to the spreading code of said first code length decide for every communication terminal interface.
