1. An apparatus comprising:
a receiver configured to receive a plurality of narrowband Internet of Things (IoT) transmissions from respective transmission devices of a plurality of transmission devices;
a processor configured to:
store an autocorrelation matrix representative of an autocorrelation of symbols comprising symbols indicative of a first narrowband IoT transmission of the plurality of narrowband IoT transmissions and symbols indicative of a second narrowband IoT transmission of the plurality of narrowband IoT transmissions, the first and second narrowband IoT transmissions received during a first time period; and
calculate an updated autocorrelation matrix based partly on the autocorrelation matrix and the autocorrelation of symbols comprising symbols indicative of the first narrowband IoT transmission received during a second time period subsequent to the first time period.
