Abstract

Spread-spectrum (SS) wireless links offer many distinct advantages including the ability to share the RF spectrum among many users, interference rejection, signal hiding, and low probability of intercept. On the transmit side, an information signal with bandwidth, B is spread into a larger RF bandwidth, B_RF. On the receive side, the signal is typically correlated with a matched signal, collapsing it back to its initial bandwidth, B. Hence, the receiver´s output signal to noise ratio (SNR) can be increased over the input SNR. These generation and gating capabilities form the basis of our impulse-modulated timehopped SS communications system
