  • Publication number: 20050152409
    Abstract: In order to increase channel capacity of a processing engine in a telecommunication network, separate telecommunication signals are multiplexed in pairs to produce at least one multiplexed signal. This signal is transmitted to the processing engine to create a processed multiplexed signal. The processed multiplexed signal from the processing engine is then demultiplexed to produce separate processed telecommunication signals.

  • Publication number: 20050141410
    Abstract: A method of reducing peak-to-average ratio in multi-carrier communications systems, involves extracting sign bits from a data stream for each sub-carrier; scrambling the sign bits; recombining the scrambled sign bits with a remaining portion of the incoming data stream to form a transmission data stream; modulating the transmission data stream; transmitting the modulated transmission data stream over a transmission medium; receiving the modulated transmission data stream; extracting the scrambled sign bits from the received transmission data stream; unscrambling the scrambled sign bits; recombining the scrambled sign bits with a remaining portion of the received transmission data stream to form a received data stream; and demodulating the received data stream.
