The M N data symbols are represented by {A(ᐉ) = a(ᐉ), for ᐉ = 0, 1, . . M N − 1}. For OFDMA, the {A(ᐉ)} are the coded data symbols themselves. 10 Typical transmitted block format [23]. 11 General frequency-domain transmitter [23]. 11. into two sets ᑾ 1 = ͭA(ᐉ)ͮᐉ = 0 M1 − 1 and ᑾ 2 = ͭA(ᐉ)ͮᐉ = M , where ᑾ 1 is mapped onto MN 1 frequency set ᑠ 1 , and ᑾ 2 is mapped onto frequency set ᑠ 2 . In the case of S > 2, ᑾ i would be mapped onto frequency set ᑠ 1 . Zeros are mapped onto the remaining N c − M N frequencies constituting the block.
Services that use the spectrum in a sporadic manner, that is, only a few times per day, are possible candidates for spectrum sharing. , WLAN in central urban areas or at airports). If no coordination between the primary and the secondary systems is possible, the extent to which spectrum sharing is possible depends strongly on the characteristics of the primary system. Properties of the secondary system that favor uncoordinated spectrum sharing are as follows: • • • Directivity of radio emissions, for example, in satellite links, radio links, or fixed wireless access with directive antennas.
Terminal A’s receiver samples the received block at a rate of 20 MHz, resulting in 1/10 the number of samples that would have resulted from sampling the entire 100-MHz band at 200 MHz. The receiver takes the (N c /10)-point DFT of the sampled block, samples the result at the frequency sets ᑠ 1 and ᑠ 2 used by the transmitter, and equalizes these samples, resulting in recovery of the transmitted data sequence. For uplink transmission from the narrowband terminal A to the base station, the process is reversed: The terminal generates a block of (N c /10) samples at the 20-MHz sampling rate, and the base station receiver, sampling at 200 MHz, takes in and processes (by DFT, sampling and equalization) a corresponding oversampled block of N c samples.
