Digital communication method, transmitter and receiver, wherein the amount of pilot symbols is selected based on the demodulator type at the receiver side

摘要

For communicating between a transmitter unit (1) and a receiver unit (2) over a communication channel using a predetermined modulation scheme, an amount of pilot symbols is selected depending on an indication of demodulator type available in the receiver unit to operate according to the predetermined modulation scheme. A set of digital symbols is modulated according to the predetermined modulation scheme to generate a modulated signal in the transmitter unit, the digital symbol set including information symbols and the selected amount of pilot symbols.
