Patent ID: 7925225

Claim:
A method of transmitting a first set of modulation symbols of a first encoded packet comprising: spreading a first subset of the first set of modulation symbols using a first subset of an orthogonal code set to generate a first spread signal, and transmitting the first spread signal on a first antenna such that each modulation symbol of the first subset of modulation symbols is spread with a respective distinct orthogonal code from the first subset of the orthogonal code set; spreading a second subset of the first set of modulation symbols using a second subset of the orthogonal code set to generate a second spread signal and transmitting the second spread signal on a second antenna such that each modulation symbol of the second subset of modulation symbols is spread with a respective distinct orthogonal code from the second subset of the orthogonal code set; the first subset of the first set of modulation symbols comprising at least two modulation symbols; and the second subset of the first set of modulation symbols comprising at least two modulation symbols.
