    Abstract: The present invention provides a device and method in multi-access communications system for reliably receiving burst transmissions from users in the presence of narrow band interference. The adaptive interference suppreser incorporates adaptive elements that are updated using a predetermined adaptation algorithm. These adaptive elements are stored in memory at the end of the burst transmission for reuse in receiving a next burst transmission.

    Abstract: A device and method for precoding data signals for pulse code modulation (PCM) transmission including a transmitter (52) for transmitting a sequence of analog levels over analog channel to a quantization device, wherein the analog channel modifies the transmitted analog levels, the transmitter (52) comprising: a mapping device (150) for mapping data bits to be transmitted to a sequence of equivalence classes, wherein each equivalence class contains one or more constellation points; and a constellation point selector (152) interconnected to the mapping device (150) which selects a constellation point in each equivalence class to represent the data bits to be transmitted and which transmits an analog level that produces the selected constellation point at an input to the quantization device.

    Abstract: The transmitter (56) for transmitting a sequence of octets over a digital network which digital network converts the octets into a sequence of levels, the transmitter including: mapping device (74) outputting for each group of data bits an equivalence class of one or more levels; a level selector (76), for selecting the level in the equivalence class to represent the group of data bits to be transmitted; a filter device (78), which receives at its input previously selected levels and provides its output to the level selector, wherein the level selector (76) selects the level to be transmitted based on the output of the filter device (78); and an octet converter (80), which receives the selected level at its input and transmits over the digital network an octet corresponding to the selected level to produce the analog signal having the predefined spectral shape when the transmitted octets are converted to levels in the digital network.
