Abstract

Wireless communication method for wireless communication from transmitter to receiver, comprising:

• • transmission step at which said transmitter transmits sequence of radio pulses as a data packet which comprises: preamble section which consists of a preamble sequence for initial symbol synchronization and channel estimation; header section which consists of both regular header information on said data packet and multiplexed preamble sequences; payload section which consists of both regular payload message of said data packet and multiplexed preamble sequences, receiving step at which said receiver receives said data packet consisting of said preamble, header and payload section.

Claims

1. Wireless communication apparatus comprising:

pulse generation means which generates a sequence of pulses;

and transmission means which transmits said sequence of pulses generated by said pulse generation means in the form of radio signal,

wherein said pulse generation means generates said sequence of pulses as a data packet, which comprises;

preamble section which consists of a preamble sequence for initial symbol synchronization and channel estimation;

header section which consists of both regular header information data for said data packet and the same preamble sequence as in said preamble section, wherein said preamble sequence is multiplexed with said regular header information data in time domain or code division;

payload section which consists of both regular payload data and the same preamble sequence as in said preamble section, wherein said preamble sequence is multiplexed with said regular payload data in the same manner as in said header section;

2. The wireless communication apparatus according to claim 1,

wherein said preamble sequence in said preamble section has a regular power level, and the power level of said multiplexed preamble sequence in said header and payload section is set to be a much lower level.

3. The wireless communication apparatus according to claim 1, which adopts the UWB (Ultra Wideband) radio signals.

10. The wireless communication apparatus according to claim 2, which adopts the UWB (Ultra Wideband) radio signals.

4. Wireless communication system for wireless communication between transmitter and receiver:

wherein said transmitter transmits a data packet consisting of a sequence of pulses, which comprises;

preamble section which consists of a preamble sequence for initial symbol synchronization and channel estimation;

header section which consists of both regular header information data and the same preamble sequence as in said preamble section, wherein said preamble sequence is multiplexed with said regular header information data in time domain or code division;

payload section which consists of both regular payload data and the same preamble sequence as in said preamble section, wherein said preamble sequence is multiplexed with said regular payload data in the same manner as in said header section;

wherein said receiver receives said data packet consisting of said preamble, header and payload section.

5. The wireless communication system according to claim 4,

wherein said preamble sequence in said preamble section has a regular power level, and the power level of said multiplexed preamble sequence in said header and payload section is set to be a much lower level.

6. The wireless communication system according to claim 4, which adopts the UWB (Ultra Wideband) radio signals.

11. The wireless communication system according to claim 5, which adopts the UWB (Ultra Wideband) radio signals.

7. Wireless communication method for wireless communication between transmitter and receiver, comprising:
