Hybrid waveform design combining OFDM and cyclic prefix based single carrier for millimeter-wave wireless communication

An apparatus for transmitting data in a wireless communication, comprising:

• a processor;
• a memory configured to be in electronic communications with the processor, the memory embodying instructions, the instructions being executable by the processor to:
• generate a first subframe, having a first cyclic prefix, for transmission based at least in part on a plurality of first pilot symbols using a first processing technique;
• generate a second subframe, having a second cyclic prefix, for transmission based at least in part on a plurality of second pilot symbols using a second processing technique;
• and
• transmit the first and second subframes.

A method for receiving data in a wireless communication, comprising:

• receiving, at a receiving device, a first subframe encoded using a first processing technique having a first cyclic prefix, and a second subframe encoded using a second processing technique having a second cyclic prefix, during a first and second time periods respectively;
• estimating initial channel conditions based in part on a plurality of first pilot symbols received, at the receiving device, in the first subframe;
• tracking channel conditions based in part on a plurality of second pilot symbols received in the second subframe;
• and
• detecting a plurality of data packets based in part on the channel estimations and in part on the channel estimation tracking information.
