WebbThe Raised Cosine Receive Filter block filters the input signal using a normal raised cosine FIR filter or a square root raised cosine FIR filter. It also downsamples the filtered signal … WebbThe RX filter is obtained by matching the transmit filter to the channel's frequency response and then convolving the result with the Raised Cosine pulse. To determine the closed-form expression for the SNR loss compared to a non-distorting band-limiting channel, we use the formula for the signal-to-noise ratio (SNR) in a band-limited channel. WebbTruncating the tails of the tx filter frequency response. This will result in degraded performance. Truncate the rx filter reponse as well. Using a non-root-raised cosine tx filter. Pick one that allows a sharper rolloff. Allocating more of the raised cosine filter to the tx, and less to the rx; Trick #2: Interfering signal has non-white spectrum. unrated eyes wide shut
