Unformatted text preview: H ( s ) 2 (b) We would like to design a system H c ( s ) that takes the received signal y ( t ) and cancels the multipath component, so that the output signal r ( t ) is the same as x ( t ) . H ( s ) H c ( s ) x ( t ) y ( t ) r ( t ) What is transfer function of of the canceller system H c ( s ) ? (c) Find the impulse response of canceller ( Hint: 1 1-x = 1 + x + x 2 + x 3 ··· for | x | < 1 ). 3. Inverse Laplace Transforms Find the Inverse Laplace transforms of the following functions (suppose the system is ra-tional and causal) (a) s ( s + 1)( s-1) (b) s + 3 ( s + 1)( s + 2) 4. Find the impulse response h ( t ) for the following Causal and Rational system. 3-6 3-5-6 1/S 1/S x(t) y(t)...
