Abstract: In a data transmitter (36) having a data encoder, an encoder (26) mode is detected. Thereafter, an excluded codeword output by the encoder operating i n the encoder mode is identified. Next, a selected bit in the excluded codewor d caused to have a predetermined value to produce a non-excluded codewword. Finally, the excluded codeword is substituted with the non-excluded codeword , wherein the non-excluded codeword is selected to mitigate effects of a decoding error in a receiver (54) associated with the excluded codeword.

Abstract: Upon receiving (101) a vocoded voice frame and detecting (102) that the received vocoded voice frame comprises an erased frame, one automatically replaces (103) the erased frame with a valid frame having at least one error condition. In a preferred approach this error condition is one that is known to cause a receiving target platform to invoke a corresponding erasure process with respect to the valid frame when received.

Abstract translation: 在接收（101）声码语音帧并且检测（102）所接收的声码语音帧包括被擦除的帧时，一个用具有至少一个错误条件的有效帧自动替换（103）已擦除的帧。 在优选方法中，该错误条件是已知的，以使得接收目标平台在接收时相对于有效帧调用相应的擦除过程。

Abstract: An apparatus (18) and method (100) provide RLP data checking. The apparatus (10) includes a frame serialization stage (20) and a bad frame filter (22) that detects possible bad frames and reclassifies these bad frames as erasures. In this manner, bad frame data are not passed to the RLP layer (16), and unnecessary resetting and resynchronization steps are avoided.
