Abstract: A wireless communication device receives OFDM radio signals having different numerologies (i.e. different sub-carrier spacing) and determines whether the transmission, by one or more transmitting nodes, of the OFDM signals are coordinated. The meaning of “coordinated” is to be understood as the OFDM signals are time-synchronized and the determination of whether the OFDM signals are coordinated may involve such actions as reading broadcast or receiving configuration message transmitted in the system, determining a relation (for instance cell/access point beam identity) between transmitted synchronization or reference signals. If the OFDM signals are determined to be coordinated, time and/or frequency offset for the second OFDM signal having the second subcarrier spacing is derived based on the time and/or frequency offset associated with the first OFDM signal having the first subcarrier spacing.

Abstract: In this work, we present a novel receiving device design for communications systems that incorporates multiple antennas at the transmitting device/receiving device. Unlike existing systems, the new system does not require prior knowledge of the channel state information (CSI) at the receiving device side to extract the information symbols from the received signal. Consequently, complexity reduction and bit error rate improvement can be jointly achieved. Moreover, the new system may offer spectral efficiency enhancement since it does not require nulling to prevent the pilot symbols as in the case of conventional systems. The results obtained show that in certain scenarios the proposed system can offer up to 15 dB of bit error rate improvement over conventional systems. Moreover, the new system can provide about 16.6% of the spectral efficiency improvement.

Abstract: A multiuser communication system comprises multiple transmitters and a multiuser receiver that detects multiple transmissions via iterative soft interference cancellation. An initial acquisition module and single user decoder module are also described. The multiuser receiver acquires and subtracts known users in the residual signal before acquiring new users in the residual signal, which is performed iteratively until no new users are detected or a stopping criterion is met. To aid receiver acquisition, the transmitters insert discrete tones into the transmitted signals.

To improve the quality of cancellation the receiver refines estimates of gain, time, frequency and phase offsets for each user after each iteration, and calculates time varying SINR estimates for each user. The multiuser receiver may be satellite based, may be a distributed receiver, or process users in parallel.
