Design of a DS/SS System using the ISM band

摘要

In this paper, it was experimented with transmission of binary data using a proposed wireless transceiver, which used direct sequence spread spectrum technique. It used the ISM band with 915MHz radio frequency and its processing gain is 557 with 10.7MHz IF signal. We were modulated of transmission data with binary phase shift keying and spread with a PN code its period is 255. To control the transmitter and receiver, we used an 8051 u-processor.
