Abstract
A network device for generating an expanded long training sequence with a minimal peak-to-average ratio. The network device includes a signal generating circuit for generating the expanded long training sequence. The network device also includes an Inverse Fourier Transform for processing the expanded long training sequence from the signal generating circuit and producing an optimal expanded long training sequence with a minimal peak-to-average ratio. The expanded long training sequence and the optimal expanded long training sequence are stored on more than 52 sub-carriers.

A wireless communications device, comprising:
- a processor configured to provide a signal generator and an Inverse Fourier Transformer, wherein the signal generator generates an extended long training sequence, wherein the Inverse Fourier Transformer processes the extended long training sequence from the signal generator and provides an optimal extended long training sequence with a minimal peak-to-average ratio, wherein at least the optimal extended long training sequence is carried by a greater number of subcarriers than a standard wireless networking configuration for an Orthogonal Frequency Division Multiplexing scheme, wherein the wireless communications device registers with an access point or a base station.
A wireless cellular device, comprising:
- a processor configured to provide a signal generator and an Inverse Fourier Transformer, wherein the signal generator generates an extended long training sequence, wherein the Inverse Fourier Transformer processes the extended long training sequence from the signal generator and provides an optimal extended long training sequence with a minimal peak-to-average ratio, and wherein at least the optimal extended long training sequence is carried by a greater number of subcarriers than a standard wireless networking configuration for an Orthogonal Frequency Division Multiplexing scheme, wherein the wireless cellular device registers with an access point or a base station.
A mobile cellular phone, comprising:
- a processor configured to provide a signal generator and an Inverse Fourier Transformer, wherein the signal generator generates an extended long training sequence, wherein the Inverse Fourier Transformer processes the extended long training sequence from the signal generator and provides an optimal extended long training sequence with a minimal peak-to-average ratio, and wherein at least the optimal extended long training sequence is carried by a greater number of subcarriers than a standard wireless networking configuration for an Orthogonal Frequency Division Multiplexing scheme, wherein the mobile cellular phone registers with an access point or a base station.
