    Abstract: A system and method for uplink channel estimation for a software defined radio is disclosed. The method comprises dividing an allocated bandwidth for a received signal on the uplink channel into N segments. The uplink channel estimation is processed for each of the N segments as a separate process. The uplink channel estimation includes pre-processing each of the N segments of the received signal; Wiener filtering the pre-processed segments of the received signal in the frequency domain; and Wiener filtering each of the frequency filtered segments in the time domain to determine a channel estimate for each of the N segments for use in equalizing the received signal.

    Abstract: A system and methods for estimating a noise power level in an uplink signal for a virtual MIMO system is disclosed. The system comprises a demodulation reference signal (DMRS) module configured to obtain a DMRS receive symbol from the uplink signal and determine a DMRS sequence for a first UE in the virtual MIMO system. An autocorrelation module is configured to calculate an average autocorrelation value for the subcarriers in the uplink signal. A cross-correlation module is configured to calculate first and second cross-correlation values of the uplink signal RZ(l) for values of l selected such that the sum of the received power from the first UE and the second UE can be accurately estimated. A noise power level module is configured to determine the noise power level for the uplink signal using the average autocorrelation value and the first and second cross correlation values.
