Frame structures, transmitters, and receivers utilizing dual subcarriers for signal adjustment
Examples of wireless OFDM communication systems are described herein which replace pilot subcarriers having known modulation with lower dual subcarriers. At the transmitter, for each resource block, the bits that modulate a few payload subcarriers are selected and then encoded with a short dual code thereby forming dual systematic bits and dual check bits. Such selected payload subcarriers are designated as upper dual subcarriers and the dual check bits modulate the lower dual subcarriers, At the receiver, for each resource block, the dual subcarriers are phase adjusted, demodulated, decoded using the short dual code, and re-modulated thereby forming the original dual subcarrier modulation without phase noise nor channel impairments. The re-modulated dual subcarriers are compared against the received dual subcarriers for channel estimation or carrier phase-locked-loop purposes. For example, prior-art OFDM systems with 4 pilots per resource block could be replaced with 8 dual subcarriers for a rate 1/2 short dual code. An increase in the number of subcarriers used for channel estimation or carrier phase-locked-loop tracking has less error in the channel estimate or phase estimate. Lower error permits lower payload BER, lower transmit power, or wider PLL bandwidth to track higher Doppler frequency shifts. |

Facilitating fast channel state information computation for 5G wireless communication systems
Fast calculation of channel state information using demodulation reference signals (DM-RS) is provided herein.
