Abstract
Se revela una estimación mejorada de los canales. En una forma de realización, la estimación inicial de los canales es llevada a cabo mediante la utilización de una secuencia de datos de entrenamiento conocidos. El paquete de datos recibido es demodulado en base a las estimaciones iniciales de los canales, desentrelazado y decodificado. Los datos decodificados son recodificados, entrelazados y modulados para generar símbolos de entrenamiento adicionales para actualizar las estimaciones de los canales a lo largo del paquete de datos recibido.An improved estimate of the channels is revealed. In one embodiment, the initial estimation of the channels is carried out by using a sequence of known training data. The received data packet is demodulated based on initial channel estimates, deinterlaced and decoded. Decoded data is recoded, interlaced and modulated to generate additional training symbols to update channel estimates throughout the received data packet.
