Abstract:
Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S 2 (i) and S 2 (i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S 1 (i) and S 1 (i)′ obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.

Claim (Index 1):
A transmitting apparatus comprising:\n a signal processor, which in operation, generates a first modulated symbol sequence and a second modulated symbol sequence, the first modulated symbol sequence obtained by sequentially mapping with a first mapping pattern that is based on a determined modulation scheme, the second modulated symbol sequence obtained by selecting, sequentially for each second modulated symbol, from the first mapping pattern and a plurality of second mapping patterns that are based on the determined modulation scheme and sequentially mapping with a selected mapping pattern; and a plurality of antennas, which in operation, transmit the first modulated symbol sequence and the second modulated symbol sequence in multi-beam signals in a same frequency and at a same time, wherein: the first mapping pattern is a mapping pattern having a different phase from phases of the plurality of second mapping patterns, and the plurality of second mapping patterns are regularly varied the first mapping pattern for each second modulated symbol.
