    Abstract: An encoder outputs a first bit sequence having N bits. A mapper generates a first complex signal s 1 and a second complex signal s2 with use of bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1, and Y indicates the number of bits used to generate the second complex signal s2. A bit length adjuster is provided after the encoder, and performs bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputs the first bit sequence after the bit length adjustment as the second bit sequence. As a result, a problem between a codeword length of a block code and the number of bits necessary to perform mapping by a set of modulation schemes is solved.

    Abstract: By a transmission method according to one aspect of the present disclosure, in a broadcasting system that generates a first broadcasting signal and a second broadcasting signal by performing multi-antenna encoding on program data, and wirelessly transmits a first broadcasting signal and a second broadcasting signal, a first transmit station transmits the first broadcasting signal, a second transmit station transmits the second broadcasting signal, the first transmit station and the second transmit station transmit the first broadcasting signal and the second broadcasting signal to an overlapping area at an identical time using an overlapping frequency band, polarized wave transmitted from the first transmit station differs from polarized wave transmitted from the second transmit station, and arrangement of the first transmit station differs from arrangement of the second transmit station.

    Abstract: An orthogonal transform subunit 14 separates a reception signal into carriers on a per-symbol basis. In a channel characteristics estimation subunit 15, (i) an SP channel characteristics estimation part 20 calculates channel characteristics at carriers to which SPs are allocated, by using signals output from the orthogonal transform subunit 14, (ii) a symbol direction interpolation part 30 interpolates, in the symbol (time) direction, signals output from the SP channel characteristics estimation part 20, (iii) a TMCC channel characteristics estimation part 40 calculates channel characteristics at carriers to which TMCCs are allocated, by using signals output from the orthogonal transfer subunit 14, and (iv) an adaptive interpolation part 50 calculates filter coefficients by using signals output from the symbol direction interpolation part 30 and the TMCC channel characteristics estimation part 40, and adaptively interpolates signals output from the symbol direction interpolation part 30 by using values of the calculated filter coefficients.
