Claim Text:
1. An electronic device that is capable of receiving data conforming to IEEE 802.11a, IEEE 802.11n and a very high throughput data (VHT-Data), comprising processing circuitry configured to: receive an IEEE 802.11a signal, a first very high throughput signal (VHT-SIG) and a second very high throughput signal (VHT-SIG), wherein the first VHT-SIG, the second VHT-SIG and the IEEE 802.11a signal are received in a single data packet; demodulate the IEEE 802.11a signal according to a first signal point location that defines a first arrangement of signal points in a signal space, wherein the IEEE 802.11a signal is modulated by a binary phase shift keying (BPSK) scheme; demodulate the first VHT-SIG according to a second signal point location that defines a second arrangement of signal points in the signal space, wherein the second signal point location is rotated by 90 degrees relative to the first signal point location; demodulate the second VHT-SIG according to the first signal point location; and demodulate a very high throughput data (VHT DATA), wherein the second VHT-SIG is in a field between a field of the first VHT-SIG and a field of the VHT Data, wherein the circuitry includes a processor which processes a software stored in a memory.
