摘要： A valid signal may be detected by initializing gain settings of the receiver section. The processing then continues by measuring received signal strength of a signal received by the receiver section to produce a 1st received signal strength indication (RSSI). The processing continues by adjusting the gain setting of the receiver section such that the 1st received signal strength indication is a predetermined offset less than a signal strength threshold. The process then continues by measuring the received signal strength of the gain adjusted representation of the signal to produce a 2nd received signal strength indication. The processing continues by appending a 2nd offset to the 2nd received signal strength value to produce an adjusted received signal strength indication value when the 2nd received signal strength value drifts from the signal strength threshold less the predetermined offset. The processing continues by measuring the received signal strength of received signals and appending the offset until a possible valid signal is detected. When the possible valid signal is detected, the gain of the receiver is adjusted based on its dynamic range.

摘要： A method and apparatus for accurately detecting the presence of a valid signal includes processing that begins by determining the energy level of an input signal in real time to produce a real time energy level. The processing then continues by delaying the input by a period of the valid signal to produce a delayed input. The processing then continues by correlating the input with the delayed input to produce a correlated input. The processing continues by determining the energy of the correlated input to produce a correlated energy level. The processing then continues by comparing the correlated energy level with the real time energy level to produce a probability that the input is a valid signal. The processing then continues by generating a valid signal probability indication based on the probability that the input is a valid signal.

摘要： A first direct current (DC) component of a first amplified representation of a received signal at an output of an amplifier set to a first gain setting is determined during a first expected idle period of a received signal. A second DC component of a second amplified representation of the received signal at the output of the amplifier set to the first gain setting is determined during a second expected idle period of the received signal. A first average DC component is determined based at least in part on the first and second DC components and a DC offset used by the amplifier when set to the first gain setting is adjusted based on a comparison of the first average DC component to one or more threshold values.

摘要： A method for field error checking begins by decoding a predetermined pattern of a field of a frame to produce a decoded pattern. The method continues by determining, for the decoded pattern, a path metric distance of a predetermined state of a plurality of states of the decoding. The method continues by comparing the path metric distance with an excepted path metric distance for the predetermined state. The method continues by indicating a field error when the path metric distance compares unfavorably with the excepted path metric distance.
