Time Domain Signal Detection for MIMO OFDM

The MIMO techniques with OFDM is regarded as a promising solution for increasing data rates, for wireless access qualities of future wireless local area networks, fourth generation wireless communication systems, and for high capacity, as well as better performance. Hence as part of continued research, in this paper an attempt is made to carry out modelling, analysis, channel matrix estimation,...

Frequency Scaled Time Domain Equalization for OFDM in Wireless Communication

In this paper, the use of Orthogonal Frequency Division Multiplexing (OFDM), combined with a Time Domain Equalizer (TEQ), is investigated for broadband fixed wireless access systems. OFDM systems use a Cyclic Prefix (CP) that is inserted at the beginning of each symbol to convert the linear convolution of data and channel into a circular one. If the CP is longer than the channel length, Inter S...

Time-Domain and Frequency-Domain Per-Tone Equalization for OFDM over Doubly-Selective Channel

In this paper, we propose new time-domain and per-tone frequency-domain equalization techniques for OFDM transmission over timeand frequencyselective channels. We present one mixed timeand frequency-domain equalizer and one per-tone frequency-domain equalizer. The mixed timeand frequency-domain equalizer (MTFEQ) consists of a one-tap time-varying (TV) time-domain equalizer (TEQ), which converts...

Generalized OFDM with Frequency-domain Equalization

Abstract A possible problem of orthogonal frequency division multiplexing (OFDM) is its high peak-to-average power ratio (PAPR). Recently, the single carrier (SC) transmission system with frequency-domain equalization is attracting much attention. In this paper, a novel approach to alleviate the PAPR problem of OFDM is proposed. A generalized OFDM (GOFDM) with frequency-domain equalization is p...
