Spread spectrum diversity transceiver

摘要

A spread-spectrum transceiver using a combination of time diversity and error-correction is disclosed. An error-correcting encoder (EC-2) encodes N-branch time-diversity signals to produce M-branch transmission signals (X-X<0>) 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 (116) decodes the M-branch received signals (V-V<0>)to produce N-branch time-diversity signals (X-X). After canceling the delay differences between the N-branch time-diversity signals, a received information signal is determined from the N received information signals according to majority logic.
