Transmitter and receiver and corresponding methods

A transmitter for transmitting signals, the transmitter comprising:

• a signal generator configured to generate the signals to be transmitted, each signal comprising one pilot sequence comprising several pilot sequence symbols,
• wherein the signal generator is configured to provide the pilot sequence based on a base sequence comprising several base sequence symbols,
• wherein the signal generator provides the pilot sequence with L pilot sequence symbols by repeating each base sequence symbol R−1 times in succession so that each base sequence symbol is present R times,
• wherein L is a natural number, and
• wherein R is a natural number greater than or equal to two and is a divisor of L,
• wherein the base sequence is configured such that a correlation of the pilot sequence with a transmission signal formed from the pilot sequence comprises a main maximum,
• wherein the pilot sequence comprises eight or twelve pilot sequence symbols,
• wherein, in the case where the pilot sequence comprises eight pilot sequence symbols, the base sequence comprises one of the following forms:
• 0010 or 1101 or 0100 or 1011, and
• wherein the zeros and ones are each the binary base sequence bits,
• wherein, in the case where the pilot sequence comprises twelve pilot sequence symbols, the base sequence comprises one of the following forms or forms acquired therefrom by reversing the bit order:
• 000101, 001011, 001101, 010001, 111010, 110100, 110010 or 101110, and
• wherein the zeros and ones are each the binary base sequence bits.
