    Abstract: A dual mode radio communication unit for a digital communication system is provided having an error controller including an error detection encoder and a forward error correction encoder which encode an input information signal into an error protected data bit stream. In addition, the communication unit includes a mode selector which enables either the error detection encoder or the forward error correction encoder used with a particular mode of operation of the communication unit. Further, a corresponding dual mode radio communication unit is provided having an error controller for generating estimated information signal samples according to a group of algorithms consisting of either an error detection algorithm or an error correction algorithm. In addition, the corresponding communication unit includes a mode selector for receiving a signal according to a particular one of the group of algorithms which is associated with a particular mode of operation of the corresponding communication unit.

    Abstract: A receiver (100) has improved signal weighting parameter estimation. The receiver receives a signal (101) having encoded data. A decision circuit (106) is coupled to the received encoded data to generate a first signal weighting parameter which is used to modify the received encoded data. The modified data is then decoded to output the decoded data. The decoded data output is then re-encoded using a technique similar to that used by the transmitter. The re-encoded data is then used to calculate a second signal weighting parameter which, in turn, is used to modify a stored replica of signal (101). The modified version of the stored replica is then decoded to yield a more accurate estimate of the information contained within the signal (101) at a receiver (100).

    Abstract: A dual mode radio communication unit (102, 104) for a digital communication system is provided having an error controller including an error detection encoder (111) and a forward error correction encoder (112) which encode an input information signal into an error protected data bit stream. In addition, the communication unit includes a mode selector which enables either the error detection encoder or the forward error correction encoder used with a particular mode of operation of the communication unit. Further, a corresponding dual mode radio communication unit is provided having an error controller for generating estimated information signal samples according to a group of algorithms consisting of either an error detection algorithm (261) or an error correction algorithm (202). In addition, the corresponding communication unit includes a mode selector (141) for receiving a signal according to a particular one of the group of algorithms which is associated with a particular mode of operation of the corresponding communication unit.

    Abstract: A diversity receiver (300) has improved diversity weighting parameter estimation. The receiver receives different versions of a signal (101) having encoded data, combines the versions and decodes the data contained within the combination. The decoded data output is then re-encoded using a similar technique as that at a transmitter which transmitted the signal (101). The re-encoded data is then used to calculate a diversity weighting parameter which is used to modify a stored replica each version. The modified versions are then combined and decoded to yield a more accurate estimate of the information contained within the signal (101) at diversity receiver (300).
