Abstract: A spread-spectrum communication system provides an effective signal-to-noise ratio (SNR) of received orthogonal frequency division multiplex (OFDM) slots in the presence of timing errors. Effective SNR can serve as a diagnostic tool for determining whether there was a timing error when a measured packet error rate (PER) remains high, and a predicted PER from the effective SNR remains low. A loop can use the effective SNR to control a time reference used by an OFDM decoder.

Abstract: Procedimiento que comprende: utilizar una referencia de tiempos actual para decodificar una pluralidad de símbolos (400) multiplexados por división de frecuencias ortogonales OFDM, en una pluralidad de intervalos de tiempo (700); medir una tasa de error de paquetes de los símbolos OFDM (400) decodificados; determinar una métrica de la relación señal-ruido, SNR, efectiva a partir de una respuesta de canal en amplitud de tonos piloto de los símbolos OFDM (400) decodificados; en base a la métrica de SNR efectiva, predecir una tasa de error de paquetes admisible; comparar la tasa de error de paquetes medida y la tasa de error de paquetes pronosticada; y en base a dicha comparación, ajustar la actual referencia de tiempos antes de decodificar el siguiente intervalo de tiempo OFDM (700).

Abstract: Exemplary embodiments are directed to communicating information relating to wireless charging. A power transmitting system includes a host device with a transmit antenna. A communication interface conveys receiver information, which includes unique identifier information, from a receiver device to the host device. A controller on the host device monitors and processes the receiver information to generate notification information, which is presented to a user on a user-perceivable notifier. The transmit antenna generates an electromagnetic field at a resonant frequency to create a coupling- mode region within a near-field of the transmit antenna. The system can detect a presence of a receiver device with a receive antenna that is in the coupling-mode region and process a request for power from the receiver device. The system can also notify a user when a host device is leaving a designated region and whether the host device includes expected receiver devices.
