Claim Text:
1. An apparatus for wireless communication, comprising: a receiver, including a filter, configured to receive a wireless signal comprising a packet, at least a portion of the wireless signal being received over a channel with a channel bandwidth of at least approximately five hundred megahertz, wherein the packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising at least one hundred and twenty-eight tones, wherein the packet further includes a cyclic prefix, wherein a duration of the cyclic prefix is a function of the channel bandwidth and is set such that the duration of the cyclic prefix is greater than a delay spread of the channel and delay introduced by front-end processing as determined by the number of taps in the filter's impulse response, wherein the delay introduced by the front end processing is inversely related to a size of the channel bandwidth; and a processor configured to evaluate the wireless signal, the processor comprising a transform module configured to convert the at least one OFDM symbol into a frequency domain signal.
