| 摘要 |
The ultra wide band communication system of the present invention includes a transmitter (station) and a receiver (station). The transmitter employs correlated spreading code such that consecutive information bits are spread with differing code. The receiver includes an analog circuit filter comprised of a cascade of unit components that appropriately de-spread and accumulate a received signal to obtain a transmitted signal without substantial hardware complexity. The unit components are substantially comprised of analog components including, a sample and hold circuit, a leaky integrator, and a multiplier.
