Bit Error Probability of Space Modulation over Nakagami-m Fading: Asymptotic Analysis

An Alternative Method to Compute the Bit Error Probability of Modulation Schemes Subject to Nakagami-m Fading

This paper presents an alternative method for determining exact expressions for the bit error probability (BEP) of modulation schemes subject to Nakagami-m fading. In this method, the Nakagami-m fading channel is seen as an additive noise channel whose noise is modeled as the ratio between Gaussian and Nakagami-m random variables. The method consists of using the cumulative density function of ...

Adaptive M-qam Modulation over Nakagami Fading Channels

We study the performance of constant-power variable-rate M-QAM schemes over Nakagami fading channels. We obtain closed-form expressions for the outage probability, spectral eeciency and average bit-error-rate (BER) assuming perfect channel estimation and negligible time delay. For a target BER of 10 ?3 , the spectral eeciency of adaptive continuous rate M-QAM comes within 5 dB of the Shannon ca...

ALOUINI AND GOLDSMITH: ADAPTIVE MODULATION OVER NAKAGAMI FADING CHANNELS 0 Adaptive Modulation over Nakagami Fading Channels

We rst study the capacity of Nakagami multipath fading (NMF) channels with an average power constraint for three power and rate adaptation policies. We obtain closed-form solutions for NMF channel capacity for each power and rate adaptation strategy. Results show that rate adaptation is the key to increasing link spectral eeciency. We analyze therefore the performance of constant-power variable...

Bit Error Rate Analysis for MC-CDMA Systems in Nakagami-m Fading Channels

Multicarrier code division multiple access (MC-CDMA) is a promising technique that combines orthogonal frequency division multiplexing (OFDM) with CDMA. In this paper, based on an alternative expression for the Q-function, characteristic function and Gaussian approximation, we present a new practical technique for determining the bit error rate (BER) of multiuser MCCDMA systems in frequency-sel...
