Abstract:Pseudorandom codes are used in direct sequence spread spectrum (DSSS) receivers to synchronize the received signals with locally generated replica. A coarse synchronization called acquisition is followed by a finer synchronization, tracking. Both of these procedures bring received and replica signals to a small timing offset and find the residual frequency modulation which is left after carrier wipe-off The acquisition stage is computationally challenging procedure for the receivers operating in weak signal co… Show more
