Abstract: A method for dynamically adjusting the power consumption of a multi-carrier receiver and a multi-carrier receiver with dynamically power adjustment. The method includes receiving a multi-carrier signal, wherein the multi-carrier signal comprises a plurality of sub-carriers. Channel characteristics of each sub-carrier are estimated according to the demodulated multi-carrier signal. ICI strength is estimated from the demodulated multi-carrier signal. A system performance is detected. The estimated ICI is subtracted when the ICI strength exceeds an ICI threshold and the system performance is less than a system performance threshold. The demodulated multi-carrier signal is then equalized is based on the estimated channel characteristics, and the system performance is updated according to the equalized multi-carrier signal.

Abstract: A wireless communication unit 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 arranged to perform a cyclic redundancy check (CRC) on the demodulated received data packets and perform multi-protocol encapsulated (MPE) decoding thereon.

Abstract: A communication system that transfers digital data on a fixed frequency channel of a radio frequency band in the presence of interference from at least one FHSS interference source includes a time diversity generation circuit. The time diversity circuit compacts a duration of data frames then replicate the time compressed data frames. The duplicated time compressed frames of data are transmitted to a communication receiver that has a time diversity data recovery circuit. The time diversity data recovery circuit buffers the received compressed and replicated data frames, evaluates whether each of the duplicated time compressed data frames are received correctly. If any one of the duplicated time compressed data frames is destroyed, the copy of the destroyed duplicated time compressed data frame is used to recover the data frame.

Abstract: A method of adaptively determining a threshold for determining whether an error associated with a frame is an erasure or the result of a discontinuous transmission (DTX) uses a sample set of recently received frames yet avoids undesirable influences on the threshold that otherwise might be caused by the number of erasures in the sample set. A disclosed example uses a histogram-based approach and a simulated sort through the histogram to determine an appropriate threshold value. In a disclosed example the lesser of a bad frame threshold guideline value and a good frame threshold guideline value provide the threshold used to distinguish between a DTX and an erasure.

Abstract: Data error often occurs during the process of data transmission or storage. Typically, a store-and-forward data switch uses the frame check sequence portion of a data frame to detect for error that occurred during transit to the switch. However, error could be introduced into the data frame when it is in the memory of the data switch. A network switch capable of single-error correction and double-error detection is provided to further protect the data frame while it is in the switch.
