In addition, there is frequency-dependent attenuation, which is approximately proportional to the square of the signal frequency. Ambient ocean acoustic noise is caused by shrimp, fish, and various mammals. Addi tionally, man-made acoustic noise exists near harbors. In spite of this hostile environment, it is possible to design and implement efficient and highly reliable underwater acoustic communication systems for transmitting digital signals over large distances. Storage Channels. Information storage and retrieval systems constitute a signif icant part of our data-handling activities on a daily basis.
8. 2) where h(t) is the impulse response of the linear filter and * denotes convolution. The Line ar Time-Variant Filter Channel. Physical channels, such as underwa ter acoustic channels and ionospheric radio channels, which result in time-variant multipath propagation of th� transmitted signal, may be characterized mathematically as time-variant linear filters. Such linear filters are characterized by the time-variant channel impulse response h ( r ; t), where ,; ( r ; t) is the response of the channel at time t , due to an impulse applied at time t - r.
Ff [x(t)] ; therefore, the system is not homogeneous. 20 + A delay system is defined by y(t) = x (t - t.. , the output is a delayed version of the input. ) . Therefore, the system is Jinear. ) + - Time-Invariant and Time-Varying Systems. A system is called time invari ant if its input-output relationship does not change with time. This means that a delayed version of an input results in a delayed version of the output. A system is time invariant if and only if, for all x(t) and all values of t0, its response to x(t - to) is y(t - t0), where y(t) is the response of the system to x(t).
