On Single-Antenna Rayleigh Block-Fading Channels at Finite Blocklength. (arXiv:1706.07778v1 [cs.IT])
来源于:arXiv
This paper concerns the maximum coding rate at which data can be transmitted
over a noncoherent, single-antenna, Rayleigh block-fading channel using an
error-correcting code of a given blocklength with a block-error probability not
exceeding a given value. A high-SNR normal approximation of the maximum coding
rate is presented that becomes accurate as the signal-to-noise ratio (SNR) and
the number of coherence intervals L over which we code tend to infinity.
Numerical analyses suggest that the approximation is accurate already at SNR
values of 15 dB and at 10 or more coherence intervals. 查看全文>>
