In uplink of interleaved single carrier frequency division multiple access (SC-FDMA) systems, multiple access interference (MAI) arises from different carrier frequency offsets (CFOs) from different users at the receiver. In this paper, the performance of uplink interleaved FDMA (IFDMA) in the presence of CFOs is exactly analyzed. An expression of signal to interference plus noise power ratio (SINR)...
As a bridge of connecting orthogonal frequency division multiplexing (OFDM) with single-carrier frequency domain equalization (SC-FDE) techniques, Vector OFDM (V-OFDM) provides significant flexibility in system design. This paper presents an analytical study of V-OFDM over multi-path fading channels. Our goal is to investigate the diversity gain and coding gain of each vector block (VB) in V-OFDM...
In multi-user multi-input multi-output (MIMO) systems, multiple timing and frequency offsets may occur in the procedure of synchronization. Conventional MIMO synchronization methods deal with timing and frequency offsets separately. In fact, these methods can not achieve the best performances because the unknown parameters will interfere with each other. In this paper, we propose a joint timing-frequency...
This paper presents a performance analysis of vector orthogonal frequency division multiplexing (VOFDM) in multipath fading channel to investigate its diversity gain, performance limitation and the choice of dimension in the vector block for the design of a low-complexity receiver. Based on the analytically derivation, it is first verified that VOFDM can realize the maximum diversity gain while the...
