NB-IoT (Narrowband Internet of Thing) technology has been adopted as standard
technology of 3GPP. NB-IoT will be spread into various business model and be expected to
grow up in future. Several types of NB-IoT receiver will be made depending on business
model. Downlink channel estimation on NB-IoT will be discussed in this paper. Average

NB-IoT (Narrowband Internet of Thing) technology has been adopted as standard technology of 3GPP. NB-IoT will be spread into various business model and be expected to grow up in future. Several types of NB-IoT receiver will be made depending on business model. Downlink channel estimation on NB-IoT will be discussed in this paper. Average method, interpolation and quasi interpolation method will be discussed in detail. Since many types of method for NB-IoT channel estimation exist, comparison among channel estimation can show what best method is. Best solution will be recommended considering resources of receiver including cost, battery, and calculation capacity.
