Abstract
A high data rate, high processing gain, direct sequence spread spectrum system that transmits a BPSK or QPSK signal. The data which are collected and stored and forwarded N bits at a time by transmitting one of 2 pseudo random waveforms every time N bits are collected. During acquisition, product devices multiply a received spread-spectrum signal by a header chip-sequence signal. After acquisition, the product device multiply the received spread-spectrum signal by 2 chip-sequence signals to generate products, with each chip-sequence signal of the chip-sequences signals being different from other chip-sequence signals of the chip-sequence signals. Integrators integrate the products thereby forming 2 correlators, and a comparator selects a largest value from the integrators. The largest value is decoded into N bits of data.
