A transmitter in a wireless network configured to utilize a pilot design and channel estimation strategy to reduce pilot overhead, the pilot design based on a channel decomposition of the channel in a ray tracing channel model. A method of using a three tiered pilot design in a millimeter wave broadband (MMB) wireless network to estimate channel state information (CSI) may include assigning a first tier pilot to a first set of resource blocks, assigning a second tier pilot to second set of resource blocks, assigning a third tier pilot in a third set of resource blocks. When two of the pilots are assigned to a common resource block, the lower tier pilot may be given preference over the higher tier pilot.
