A scalable radio platform for wireless communication systems which interfaces with either user equipment or system equipment to allow system parameters to be modified such that users of different communication systems can communicate with each other and also allows a wireless communication system to adapt to changing radio conditions.

Scalable radio platform

The encoding/transmission of information in an OFDM system is enhanced by using complementary codes. The complementary codes, more particularly, are converted into phase vectors and the resulting phase vectors are then used to modulate respective carrier signals. The modulated result is then transmitted to a receiver which decodes the received signals to recover the encoded information.

OFDM digital communications system using complementary codes

The encoding/transmission of information in an OFDM system is enhanced by using complementary codes and different patterns of amplitude modulation representing respective data words. The complementary codes, more particularly, are converted into phase vectors and modulated by the selected pattern. The result is then used to modulate respective carrier signals. The modulated result is then transmitted to a receiver which decodes the received signals to recover the encoded information.
