Improving LTE Uplink Reliability

DUEL, designed as an algorithmic and DSP extension to LTE base station receiver designs, requires no changes to handsets.

Cambridge Consultants' patent pending DUEL receiver take advantage of properties of the LTE uplink signal to reconstruct what was transmitted with higher fidelity than a conventional text-book receiver. As a result, it works well even when the signals received by each BS antenna are highly correlated.
