WebM = 64; bitsPerSym = log2 (M); Generate random bits. When operating in bit mode, the length of the input data must be an integer multiple of the number of bits per symbol. x = randi ( [0 1],10*bitsPerSym,1); Modulate the input data using a binary symbol mapping. Set the modulator to output fixed-point data. WebAug 23, 2024 · With 1024 QAM modulation, there are more bits per symbol — 10 bits per symbol versus 8 bits in 256 QAM. More bits equals more data, and the payload delivery of data is more efficient — like having a bigger truck. At the same time, OFDMA decreases the spaces between the subcarriers, packing even more resource units into the truck, so to …

WebMar 25, 2024 · If you encode only one bit per symbol, all the energy in that symbol represents that single bit. But, if you encode N states (log2(N) bits) onto each symbol, each bit effectively gets only a portion of the energy of the symbol. On the other hand, the noise energy of each bit in a symbol does not divide. This is the key point to grasp. In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time. The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s).

WebFeb 4, 2024 · b) (4 points) For part (a), what is the theoretical number of bits per symbol needed to achieve this 33.6 kb/s? This question is where I got stock I computed the # of symbols to be 43 then I computed the bandwidth / # of symbols (so, 3100/43) which is almost 72 bits/symbol I think its incorrect. The last question is WebThe bits per symbol is the (modulation's power of 2) × (Forward Error Correction). So for example, in 64-QAM modulation 64 = 2 6 so the bits per symbol is 6. The Forward Error Correction (FEC) is usually expressed as a fraction; i.e., 1/2, 3/4, etc.
