Patent ID: 7460611

Claim:
A communication system for increasing a capacity by implementing one-frequency reuse with a non-spread spectrum system, wherein: a transmitting station side including at least two sending stations each corresponding to a respective user, and employing a different interleave method configured to transmit a transmission signal obtained by segmenting transmission information into a plurality of frames, encoding each frame, power amplifying each encoded signal with a different amplitude, and interleaving all signals with each amplified signal collected into one channel; and a receiving station side configured to reproduce said transmission channel signal into original segmental frames by de-interleaving said transmitting signal from the at least two sending stations in correspondence to each different interleave method, sequentially decoding codes of the signal in descending order of Signal-to-Interference and Noise power Ratio, and re-encoding the decoded signal to successively cancel the re-encoded signal from said transmission signal, wherein the transmitting station side is configured to monitor propagation path conditions such as traffic conditions at certain intervals to update an amplitude value of each code with reference to a number of interference signals satisfying predetermined criteria, defining considerable interference signals, updated number of code words for one frame, and noise power according to said propagation path conditions.
