FreshPatents.com Methods and apparatuses for dealing with spectrum inversion
An apparatus of processing a time domain synchronous orthogonal frequency-division-multiplexing (TDS-OFDM) signal is provided. The apparatus includes a receiving block and a demodulating block. The receiving block receives the TDS-OFDM signal, and generates a down-converted signal according to the received TDS-OFDM signal. The demodulating block is coupled to the receiving...

FreshPatents.com Equalizer for am in-band on-channel radio receivers
A method is provided for equalizing OFDM symbol vectors received on AM in-band on-channel radio signal including a main carrier and first and second BPSK modulated subcarriers. The method comprises the steps of: computing a BPSK magnitude signal; filtering the BPSK magnitude signal; filtering complex samples received on the main...

FreshPatents.com Test apparatus and program
Provided is a measurement apparatus that measures power of an orthogonal frequency division multiplexing modulated signal (OFDM modulated signal) output from a transmitting device, comprising an output control section that causes the transmitting device to output the OFDM modulated signal having a prescribed waveform that repeats in each of a...

FreshPatents.com Method and communication system device for the generation or processing of ofdm symbols in a transmission system with spread user data
OFDM symbols are generated using data from one or more users or from one or more data sources represented on a number of sub-carriers. To inhibit multiple-access interference on application of the CDMA principle, the data are transformed in a data-source specific manner and only subsequently allocated to the sub-carriers,...

FreshPatents.com Multi-band ofdm communications system
A method for providing communication in a wireless network comprising one or more simultaneously operating pico networks includes dividing UWB spectrum into a plurality of frequency bands. These bands are formed into band groups. At least one band group is assigned to each one of the pico networks. At least...
