Abstract
A transmission method of a wireless signal including the following steps is provided. Multiple orthogonal frequency division multiplexing (OFDM) symbols carried by multiple subcarriers are generated according to a data signal. A scrambling pattern including multiple scrambling symbols is generated, wherein the scrambling symbols respectively correspond to the subcarriers in the frequency domain. The scrambling symbols corresponding to two contiguous subcarriers are correlated. The scrambling symbols are utilized to encode the OFDM symbols carried by the corresponding subcarriers.
Claims22
A transmission method of a wireless signal, comprising:
- a. generating a plurality of orthogonal frequency division multiplexing (OFDM) symbols according to a data signal, wherein the OFDM symbols are carried by a plurality of subcarriers;
- b. generating a scrambling pattern comprising a plurality of scrambling symbols respectively corresponding to the subcarriers in the frequency domain, wherein the scrambling symbols corresponding to two contiguous subcarriers are correlated;
- and
- c. utilizing the scrambling symbols to encode the OFDM symbols carried by the corresponding subcarriers.
A transmitter of a wireless signal, comprising:
- an OFDM multiplexer for generating a plurality of OFDM symbols according to a data signal, wherein the OFDM symbols are carried by a plurality of subcarriers;
- and
- a correlated scrambler for generating a scrambling pattern, wherein a plurality of scrambling symbols of the scrambling pattern are utilized to encode the OFDM symbols carried by the corresponding subcarriers;
