Abstract:
1. A wireless communications device comprising: a receiver including a demodulator and a decoder configured to demodulate and decode a current signal from an orthogonal frequency division multiplexing (OFDM)-based air interface based on previously detected signals, detect decoding errors for the current signal, determine whether the detected decoding errors exceed a predetermined decoding error threshold, and in response to determining that the detected decoding errors exceed the predetermined error threshold: a processor configured to assign a quality score to each of the plurality of OFDM networks based on the acquired signals, determine one of the plurality of OFDM networks having a highest quality score, and determine whether the current signal is provided by the one of the plurality of OFDM networks having the highest quality score; and a user interface configured to display a query and receive from a user of the device a command related to selecting the determined one of the plurality of networks, wherein the query is displayed in response to a determination that the current signal is not provided by the determined one of the plurality of OFDM networks having the highest quality score, wherein the receiver, controlled by the processor, is configured to change from decoding the current signal to decoding a signal of the determined one of the plurality of OFDM networks having the highest quality score based on the received user command.
