  • Patent number: 4261053
    Abstract: A PSK modulator employs a waveform of the overlapped raised cosine type which results in reduced adjacent channel interference. Waveforms of the overlapped raised cosine type include the overlapped raised cosine waveform itself as well as waveforms substantially similar thereto. Such waveforms can be produced, in a PSK modulator, by employing a Thomson filter with a single attenuation pole. Employing such a filter with a time bandwidth product (BT) of 1.2 provides the overlapped raised cosine waveform. However, changing the Thomson filter's BT product to 1.0 to thereby generate a waveform of the overlapped raised cosine type provides even further improvements in adjacent channel interference.
