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...

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...

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...
