Abstract
Multicarrier frequency hopping (MCFH) modulation is a multicarrier modulation technique, which unlike orthogonal frequency division multiplexing (OFDM), does not require centralized frequency assignment. In a MCFH system, the available bandwidth is divided into subbands, which respectively are divided into subchannels. The transmitter randomly selects one subchannel from each subband, and simultaneously transmits data over the chosen subchannels. In this paper we study the uplink performance of multicarrier frequency hopping systems over slow fading channels. We model users spatial distribution by a homogeneous Poisson point process (PPP), and study the expected capacity of such systems. Through our numerical simulations, we show how optimizing the system parameters such as the number of subbands can increase the systems throughput.
