Claim Text:
1. Non-transitory computer storage media having computer-executable instructions embodied thereon that, when executed, enable a computing device to perform a method for dynamically enabling cyclic prefix based on increased distortion levels within a channel, the method comprising: receiving one or more inputs indicating a level of intersymbol interference (ISI) within one or more channels; receiving an indication of a predetermined threshold level of ISI for the one or more channels; determining that the level of ISI within at least one channel of the one or more channels is greater than or equal to the predetermined threshold level; and upon determining that the level of ISI within the at least one channel is greater than or equal to the predetermined threshold level, dynamically enabling a downlink cyclic prefix within the at least one channel; determining, when the downlink cyclic prefix is enabled, that the level of ISI within the at least one channel is less than the predetermined threshold level; and upon determining that the level of ISI within the at least one channel is less than the predetermined threshold level, dynamically disabling the downlink cyclic prefix within the at least one channel, such that no downlink cyclic prefix is enabled within the channel.
