Bandwidth-efficient pilot symbol aided technique with diversity reception in land mobile satellite fading channels
Man Hung Ng, Siu Wun Cheung · 2003
A bandwidth-efficient pilot symbol aided technique for fading compensation and diversity combining is proposed for use with trellis-coded modulation (TCM) in land mobile satellite fading channels. Computer simulation tests are used to assess the effects of the technique on the bit-error-rate (BER) performances of trellis-coded 16-ary quadrature-amplitude-modulation in the shadowed Rician fading channels. Results have shown that the proposed technique requires a low bandwidth redundancy to achieve good BER performances and is suitable for use with TCM and diversity reception.
