Title: Spread spectrum diversity transceiver

Abstract: A spread-spectrum transceiver using a combination of time diversity and error-correction is disclosed. An error-correcting encoder encodes N-branch time-diversity signals to produce M-branch transmission signals consisting of N-branch information-bit signals and (M-N)-branch check-bit signals. The M-branch transmission signals are transmitted according to spread-spectrum system. At a receiving side, an error-correcting decoder decodes the M-branch received signals to produce N-branch time-diversity signals. After canceling the delay differences between the N-branch time-diversity signals, a received information signal is determined from the N received information signal according to majority logic.
