    Abstract: An error detection system (200; 508) for a discrete receiver (340). The error detection system (200; 508) indicates bad frames of binary information signals (206; 408) which contain distorted bits in densities so great as to cause a convolutional decoder (212; 412) to generate an incorrect, decoded signal. A signal (418) decoded by a convolutional decoder (212; 412) is re-encoded by an encoder (224; 424), and the re-encoded signal (230; 430) is compared (256; 456) with the signal (206-248; 408-448) received by the receiver (340). When portions of the re-encoded signal (230; 430) differ too greatly from the actual, received signal (206-248; 408-448), a bad frame indication (286; 486) is generated.

    Abstract: A method and apparatus is disclosed (Fig. 3) for improving the quality of speech samples communicated via sub-band coding utilizing adaptive bit allocation (Fig. 1), by providing error detection only on the adaptive bit allocation information. A first error detection code (340), such as a cyclic redundancy check (CRC), is calculated on the bit allocation parameters (330) in the transmitter (130) and sent to the receiver (180), where a second error detection code (370) is calculated based upon the reconstructed bit allocation parameters (360). The transmitted error detection code is then used to determine (380) if the received bit allocation information is correct, and if not, the frame of speech data is discarded. By protecting only the bit allocation information, additional speech frames may be salvaged from the error-prone channel, thus further increasing speech intelligibility.

    Abstract: A method, system, network and device provide Smart Grid RFI detection. One or more symbols or chips present in one or more received radio frequency signals are detected and the presence of one or more erred symbols or chips in the detected one or more symbols present in the received one or more radio frequency signals determined. A correlation in time between the one or more erred symbols or chips and an infrastructure waveform associated with electrical infrastructure can be determined. When the determined correlation indicates the electrical infrastructure as a source of detectable radio frequency interference to a device, a pattern flag is generated. The pattern flag or pattern flag representation can be stored and/or transmitted.

    Abstract: A wireless communication unit (400) comprises a receiver for receiving information from a remote transmitter unit. The receiver comprises a demodulator for demodulating received data packets operably coupled to a decoder (480) arranged to perform a cyclic redundancy check (CRC) on the demodulated received data packets and perform multi-protocol encapsulated (MPE) decoding thereon. The demodulator forwards both valid CRC corrected data packets and non-corrected CRC data packets to the decoder (480) and the decoder (480) is configured to place the MPE non-corrected CRC data packets into Reed Solomon (RS) code words.
